b6431a0131 ALSA: cs4236: fix error return comparison of an unsigned integer 
commit d60229d84846a8399257006af9c5444599f64361 upstream.

The return from pnp_irq is an unsigned integer type resource_size_t
and hence the error check for a positive non-error code is always
going to be true.  A check for a non-failure return from pnp_irq
should in fact be for (resource_size_t)-1 rather than >= 0.

Addresses-Coverity: ("Unsigned compared against 0")

d88417a657 ALSA: sb8: add a check for request_region 
[ Upstream commit dcd0feac9bab901d5739de51b3f69840851f8919 ]

In case request_region fails, the fix returns an error code to
avoid NULL pointer dereference.
