2008-08-05cs5520: add enablebits checkingBartlomiej Zolnierkiewicz
Based on sparse comments in OpenFirmware code (no Cx5510/Cx5520 datasheet here). This fixes 2.6.26 regression reported by TAKADA and caused by addition of warm-plug support. Tested-by: TAKADA Yoshihito <takada@mbf.nifty.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-08-05ide-cd: fix endianity for the error message in cdrom_read_capacityPetr Tesarik
Aesthetic regards aside, commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 still leaves a bug in the error message, because it uses the unconverted big-endian value for printk. Fix this by using a local variable in machine byte order. The result is correct, more readable, and also produces slightly shorter code on i386.

2008-08-05ide: remove CONFIG_IDE_MAX_HWIFSAdrian Bunk
The benefits of a user settable CONFIG_IDE_MAX_HWIFS have become pretty tiny and are no longer considered worth the trouble of an own option. Simply always #define MAX_HWIFS to 10. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Fix it by calling ide_device_get() before kref_get() and ide_device_put() after kref_put() in all affected device drivers. v2: Brown paper bag time. In v1 cd->drive was referenced after dropping last reference on cd object (which could result in OOPS in ide_device_put() as reported/debugged by Mariusz Kozlowski). Fix it by caching cd->drive in the local variable (fix other device drivers too).

Fix byte-swapping for id->words161_175[], id->words206_254[] and id->words206_254[]. Luckily all words previously left in little-endian byte-order are marked as reserved so this fix shouldn't affect user-space applications. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-07-24ide: fix for EATA SCSI HBA in ATA emulating modeBartlomiej Zolnierkiewicz
IDE probing code used to skip devices attached to EATA SCSI HBA in ATA emulating mode but because of warm-plug support port I/O resources are no longer freed if no devices are detected on a port and the decision about the driver to use is left up to the user.
