[alsa-devel] [PATCH][next] ASoC: rsnd: make main_rate signed to check for -ve error return codes

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The comparison of main_rate < 0 has no effect because main_rate is
an unsigned int. Make it signed so that any -ve error returns from the
call to rsnd_clk_query can be detected.

Detected by CoverityScan, CID#1446152 ("Unsigned compared against 0")

Fixes: ef4cf5d6a143e0 ("ASoC: rsnd: add rsnd_ssi_clk_query()")
