HID: dragonrise: fix HID Descriptor for 0x0006 PID

2016-01-05T17:39:14+00:00

commit 18339f59c3a6698ee17d32970c9e1e450b16e7c3 upstream.

Fixed HID descriptor for DragonRise Joystick.  Replaced default descriptor
which doubles Z axis and causes mixing values of X and Z axes.

gpio/omap: raw read and write endian fix

2016-01-05T17:38:56+00:00

commit 661553b9c67c1c7496de5f603ee3d338ecad6850 upstream.

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

PM / devfreq: Fix incorrect type issue.

2016-01-05T17:38:22+00:00

commit 5f25f066f75a67835abb5e400471a27abd09395b upstream.

time_in_state in struct devfreq is defined as unsigned long, so
devm_kzalloc should use sizeof(unsigned long) as argument instead
of sizeof(unsigned int), otherwise it will cause unexpected result
in 64bit system.

PM / devfreq: Fix governor_store()

2016-01-05T17:37:46+00:00

commit 14a21e7ba8cf6eab968310c92ca19a00f13ce3d9 upstream.

Writing the currently set governor into sysfs currently
seems to fail.
Fix this by setting the return code to zero before
leaving governor_store().

cdrom: Random writing support for BD-RE media

2016-01-05T17:36:52+00:00

commit f7e7868b4743f1cc5e59e6e0ddd3ccf9cfe53a1b upstream.

Recently, i bought a blu-ray writer and noticed that while cdrecord
worked perfectly, random writing didn't work on rewritable bd-re media.
For example, dd if=/dev/zero of=/dev/sr0 bs=32768 count=2 gave the usual
"read-only file system" message.

After checking if the problem lies with my burner or firmware, i grep-ed
the kernel source for EROFS. One of the results was in the cdrom driver.

I tried to follow the function chain and ended in the cdrom_is_dvd_rw
function where writing is permitted only for DVD-RAM and DVD+RW media.
I added a new case label for 0x43 which is the profile name of BD-RE
and now it works correctly for BD-RE too.

Maybe there is a better way of implementing this, like a new function
checking for blu-ray support and called from cdrom_open_write like
it happens for mrw and dvdram media, but adding the case label worked.

Thank you for your time.
