This patch series fixes the behavior of the corsair-cpro driver while
hidraw is used from userspace.

The first patch introduces a separate buffer for sending commands to
the device to prevent it from being overwritten thanks to a hidraw
userspace call.

The second patch replaces the complete() call in the raw event parsing
function with complete_all() to signify that the completion is done
until reinit.

The third patch introduces locking for the ccp->wait_input_report
completion as it's touched in functions that could be executing in
parallel.

Aleksa Savic (3):
hwmon: (corsair-cpro) Use a separate buffer for sending commands
hwmon: (corsair-cpro) Use complete_all() instead of complete() in
ccp_raw_event()
hwmon: (corsair-cpro) Protect ccp->wait_input_report with a spinlock
