[PATCH 00/15] staging: comedi: cleanup NULL pointer checks

[H Hartley Sweeten]

For aesthetics, change all the NULL comparisons from (foo == NULL) to (!foo)
and (foo != NULL) to simply (foo).

In addition, remove the NULL pointer checks of the 'cmd' in the s626 driver.
The 'cmd' is the address of a member variable in a struct. It will always
be valid.
