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")
Fixes: a9824c868a2c ("[ALSA] Add CS4232 PnP BIOS support")
