[PATCH 5.17 0397/1126] ASoC: fsi: Add check for clk_enable

[Greg Kroah-Hartman]

From: Jiasheng Jiang <jiasheng@xxxxxxxxxxx>

[ Upstream commit 405afed8a728f23cfaa02f75bbc8bdd6b7322123 ]

As the potential failure of the clk_enable(),
it should be better to check it and return error
if fails.

Fixes: ab6f6d85210c ("ASoC: fsi: add master clock control functions")
