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

--Changes in v2: Report the error code is being returned rather than squashing it down to -ENODEV.
