[alsa-devel] [PATCH] ASoC: wm8741: Remove unneeded startup() callback

[Sergej Sawazki]

Do not apply rate constraints in the startup() callback. The machine driver
can change the sysclk and hence the supported frame rates in its hw_params().
This callback is unneeded since commit e369bd006fd6 ("ASoC: wm8741: Allow
master clock switching").
