2008-03-07gigaset: fix Oops on module unload regressionTilman Schmidt
The card state mutex was only initialized when a device was connected, but used during unload unconditionally, leading to an Oops if a driver was loaded and unloaded again without ever connecting a device. Fix this by initializing the mutex as soon as the structure is allocated. Also add a missing mutex unlock revealed in the same execution path. This fixes a possible Oops in 2.6.25-rc that was introduced by commit e468c04894f36045cf93d1384183a461014b6840 ("Gigaset: permit module unload"). Thanks to Roland Kletzing for reporting this problem.

2008-03-04hisax_fcpcipnp: move request_irq later in probeKyle McMartin
After a quick glance at the code, we're getting the DEBUG_SHIRQ spurious interrupt before we have the adapter template filled in. Real interrupts appear to be turned on by fcpci*_init(), so move request_irq until just before that.

2008-03-04drivers/isdn: correct use of ! and &Julia Lawall
In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337 ("wmi: (!x & y) strikes again"), a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Karsten Keil <kkeil@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This can be broken down into these major areas: - Documentation updates (language translations and fixes, as well as kobject and kset documenatation updates.) - major kset/kobject/ktype rework and fixes. This cleans up the kset and kobject and ktype relationship and architecture, making sense of things now, and good documenation and samples are provided for others to use. Also the attributes for kobjects are much easier to handle now. This cleaned up a LOT of code all through the kernel, making kobjects easier to use if you want to. - struct bus_type has been reworked to now handle the lifetime rules properly, as the kobject is properly dynamic. - struct driver has also been reworked, and now the lifetime issues are resolved. - the block subsystem has been converted to use struct device now, and not "raw" kobjects. This patch has been in the -mm tree for over a year now, and finally all the issues are worked out with it. Older distros now properly work with new kernels, and no userspace updates are needed at all. - nozomi driver is added. This has also been in -mm for a long time, and many people have asked for it to go in. It is now in good enough shape to do so. - lots of class_device conversions to use struct device instead.

2008-01-04[ISDN]: i4l: Fix DLE handling for i4l-audioMatthias Goebl
The DLE handling in i4l-audio seems to be broken. It produces spurious DLEs so asterisk 1.2.24 with chan_modem_i4l gets irritated, the error message is: "chan_modem_i4l.c:450 i4l_read: Value of escape is ^ (17)". -> There shouldn't be a DLE-^. If a spurious DLE-ETX occurs, the audio connection even dies. I use a "AVM Fritz!PCI" isdn card. I found two issues that only appear if ISDN_AUDIO_SKB_DLECOUNT(skb) > 0: - The loop in isdn_tty.c:isdn_tty_try_read() doesn't escape a DLE if it's the last character. - The loop in isdn_common.c:isdn_readbchan_tty() doesn't copy its characters, it only remembers the last one ("last = *p;"). Compare it with the loop in isdn_common.c:isdn_readbchan(), that *does* copy them ("*cp++ = *p;") correctly. The special handling of the "last" character made it more difficult. I compared it to linux-2.4.19: There was no "last"-handling and both loops did escape and copy all characters correctly.

2008-01-04[ISDN] i4l: 'NO CARRIER' message lost after ldisc flushMatthias Goebl
The ISDN tty layer doesn't produce a 'NO CARRIER' message after hangup. I suppose it broke when tty_buffer_flush() has been added to tty_ldisc_flush() in the commit below. For isdn_tty_modem_result(RESULT_NO_CARRIER..) the message inserted via isdn_tty_at_cout() -> tty_insert_flip_char() is flushed immediately by tty_ldisc_flush() -> tty_buffer_flush(). More annoyingly, the audio abort sequence DLE-ETX is also lost. This patch fixes only active audio connections, because I assume that nobody changes the line discipline for audio. For non-audio connections the problem remains. Maybe we can remove the tty_ldisc_flush() in isdn_tty_modem_result() at all because it's done at tty_close?

The box has no HiSax card installed. the reason for the crash is add_timer() done on an already running timer. This happens because for some reason CARD_INIT is called twice. this patch works this problem around by using mod_timer() - this gets a booting system - but it would be nice to figure out why CARD_INIT is done twice. the ISDN config section (generated via make randconfig) is this: # # ISDN feature submodules # # CONFIG_ISDN_DRV_LOOP is not set CONFIG_ISDN_DIVERSION=y # # ISDN4Linux hardware drivers # # # Passive cards # CONFIG_ISDN_DRV_HISAX=y # # D-channel protocol features # CONFIG_HISAX_EURO=y CONFIG_DE_AOC=y # CONFIG_HISAX_NO_SENDCOMPLETE is not set # CONFIG_HISAX_NO_LLC is not set # CONFIG_HISAX_NO_KEYPAD is not set CONFIG_HISAX_1TR6=y CONFIG_HISAX_NI1=y CONFIG_HISAX_MAX_CARDS=8 # # HiSax supported cards # CONFIG_HISAX_16_0=y # CONFIG_HISAX_16_3 is not set # CONFIG_HISAX_TELESPCI is not set CONFIG_HISAX_S0BOX=y # CONFIG_HISAX_AVM_A1 is not set CONFIG_HISAX_FRITZPCI=y CONFIG_HISAX_AVM_A1_PCMCIA=y CONFIG_HISAX_ELSA=y CONFIG_HISAX_IX1MICROR2=y CONFIG_HISAX_DIEHLDIVA=y # CONFIG_HISAX_ASUSCOM is not set # CONFIG_HISAX_TELEINT is not set CONFIG_HISAX_HFCS=y # CONFIG_HISAX_SEDLBAUER is not set CONFIG_HISAX_SPORTSTER=y # CONFIG_HISAX_MIC is not set # CONFIG_HISAX_NETJET is not set # CONFIG_HISAX_NETJET_U is not set # CONFIG_HISAX_NICCY is not set # CONFIG_HISAX_ISURF is not set # CONFIG_HISAX_HSTSAPHIR is not set # CONFIG_HISAX_BKM_A4T is not set # CONFIG_HISAX_SCT_QUADRO is not set # CONFIG_HISAX_GAZEL is not set # CONFIG_HISAX_HFC_PCI is not set # CONFIG_HISAX_W6692 is not set # CONFIG_HISAX_HFC_SX is not set # CONFIG_HISAX_DEBUG is not set # # HiSax PCMCIA card service modules # # # HiSax sub driver modules # CONFIG_HISAX_ST5481=y CONFIG_HISAX_HFCUSB=y # CONFIG_HISAX_HFC4S8S is not set CONFIG_HISAX_FRITZ_PCIPNP=y CONFIG_HISAX_HDLC=y # # Active cards # CONFIG_ISDN_DRV_ICN=m CONFIG_ISDN_DRV_PCBIT=m CONFIG_ISDN_DRV_SC=y # CONFIG_ISDN_DRV_ACT2000 is not set CONFIG_HYSDN=m # CONFIG_ISDN_DRV_GIGASET is not set # CONFIG_ISDN_CAPI is not set CONFIG_PHONE=y CONFIG_PHONE_IXJ=m Signed-off-by: Ingo Molnar <mingo@elte.hu> Cc: Karsten Keil <kkeil@suse.de> Cc: Kai Germaschewski <kai@germaschewski.name> Cc: "Rafael J.
