[PATCH -next] ASoC: amd: Fix an ignored error return from platform_get_irq_byname()

[Yang Li]

The return from the call to platform_get_irq_byname() is int, it can be
a negative error code, however this is being assigned to an unsigned
int variable 'adata->i2s_irq', so assign the value to 'ret' concurrently
to solve this problem without affecting other functions.

Eliminate the following coccicheck warning:
./sound/soc/amd/acp/acp-renoir.c:286:5-19: WARNING: Unsigned expression
compared with zero: adata -> i2s_irq < 0
