staging/rts5208: fix incorrect shift to extract upper nybble 2017-09-13T21:09:44+00:00 Colin Ian King colin.king@canonical.com 2017-08-18T13:34:16+00:00 f3584d55a8d8d0cff5a423e81162e069693c1914 commit 34ff1bf4920471cff66775dc39537b15c5f0feff upstream. The mask of sns_key_info1 suggests the upper nybble is being extracted however the following shift of 8 bits is too large and always results in 0. Fix this by shifting only by 4 bits to correctly get the upper nybble.

There is a clean-up bug in the core comedi module initialization functions, `comedi_init()`. If the `comedi_num_legacy_minors` module parameter is non-zero (and valid), it creates that many "legacy" devices and registers them in SysFS. A failure causes the function to clean up and return an error. Unfortunately, it fails to destroy the "comedi" class that was created earlier. Fix it by adding a call to `class_destroy(comedi_class)` at the appropriate place in the clean-up sequence.
