USB: Fix a bug on appledisplay.c regarding signedness

2010-01-06T22:26:33+00:00

commit 37e9066b2f85480d99d3795373f5ef0b00ac1189 upstream. brightness status is reported by the Apple Cinema Displays as an 'unsigned char' (u8) value, but the code used 'char' instead. Note that he driver was developed on the PowerPC architecture, where the two types are synonymous, which is not always the case. Fixed that. Otherwise the driver will interpret brightness levels > 127 as negative, and fail to load. Signed-off-by: pancho horrillo Signed-off-by: Greg Kroah-Hartman

USB: emi62: fix crash when trying to load EMI 6|2 firmware

2010-01-06T22:26:32+00:00

commit ac06c06770bb8761b1f1f9bdf2f5420fa6d3e9fa upstream. While converting emi62 to use request_firmware(), the driver was also changed to use the ihex helper functions. However, this broke the loading of the FPGA firmware because the code tries to access the addr field of the EOF record which works with a plain array that has an empty last record but not with the ihex helper functions where the end of the data is signaled with a NULL record pointer, resulting in: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [] emi62_load_firmware+0x33c/0x740 [emi62] This can be fixed by changing the loop condition to test the return value of ihex_next_binrec() directly (like in emi26.c).

USB: usbtest: no need for USB_DEVICEFS

2009-07-28T21:31:11+00:00

THis patch (as1270) allows the usbtest module to be built even when USB_DEVICEFS isn't configured. Tests can be performed without USB_DEVICEFS, using the /dev/bus/usb/*/* device files. Signed-off-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Signed-off-by: Alexey Dobriyan Signed-off-by: Linus Torvalds

USB: make transfer_buffer_lengths in struct urb field u32

2009-03-24T23:20:36+00:00

Roel Kluin pointed out that transfer_buffer_lengths in struct urb was declared as an 'int'. This patch changes this field to be 'u32' to prevent any potential negative conversion and comparison errors. This triggered a few compiler warning messages when these fields were being used with the min macro, so they have also been fixed up in this patch. Cc: Roel Kluin Signed-off-by: Greg Kroah-Hartman
