Subject: [PATCH] ASoC: dwc: Remove check in set_bclk_ratio handling
A check added to dw_i2s_set_bclk_ratio that the data format is
consistent with the ratio seems reasonable but breaks when the
ratio is changed before the format. Remove the check - it is
unnecessary.
See: https://github.com/raspberrypi/linux/issues/5724
Fixes: 9c6694c24f26 ("ASOC: dwc: Fix 16-bit audio handling")
