[media] xc4000: code cleanup
Various coding style changes: - removed unused / commented out code - changed C++ style comments to C format - renamed functions and variables that included upper case letters in the name - removed tabs from module parameter descriptions - replaced the use of XC_RESULT_* with standard error codes Signed-off-by: Istvan Varga <istvan_v@mailbox.hu> Cc: Patrick Boettcher <pboettcher@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>hifive-unleashed-5.1
