There is an omitted unlock in mdc800_usb_probe's fail path. Add it. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Cc: Henning Zabel <henning@uni-paderborn.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-10-17USB: remove err() macro from more usb driversGreg Kroah-Hartman
USB should not be having it's own printk macros, so remove err() and use the system-wide standard of dev_err() wherever possible. In the few places that will not work out, use a basic printk(). Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-10-17USB: remove info() macro from remaining usb driversGreg Kroah-Hartman
USB should not be having it's own printk macros, so remove info() and use the system-wide standard of dev_info() wherever possible. In the few places that will not work out, use a basic printk(). Clean up the remaining usages of this in the drivers/usb/ directory. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-02-01USB: Drop unnecessary continue in a few driversJulia Lawall
Continue is not needed at the bottom of a loop. The semantic patch implementing this change is as follows: @@ @@ for (...;...;...) { ... if (...) { ... - continue; } } Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-19USB: image: mdc800: clean up urb->status usageGreg Kroah-Hartman
This done in anticipation of removal of urb->status, which will make that patch easier to review and apply in the future. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2007-02-07USB: race on disconnect in mdc800Oliver Neukum
I overlooked one. Setting the flag and killing the URBs must be under the lock so that no URB is submitted after usb_kill_urb() Signed-off-by: Oliver Neukum <oliver@neukum.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
