Subject: [PATCH] ASoC: ti: davinci-evm: Do not fail if the dai_set_sysclk returns -ENOTSUPP
Git-commit: 69f34053f883a53e86fa8ff7b99a81d8b5d50dae
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518
The davinci McBSP (davinci-i2s) driver does not implement the set_sysclk
callback, which is fine and should not be treated as error.
