USB: Fix a bug on appledisplay.c regarding signedness

2010-01-06T23:03:39+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.

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

2010-01-06T23:03:37+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: usblcd, fix memory leak

Stanse found a memory leak in lcd_probe. Instead of returning without
releasing the memory, jump to the error label which frees it.
