This patch fixes below two uninitialized symbol warnings
warning: sound/soc/codecs/wcd938x.c:2092 wcd938x_tx_swr_ctrl() error: uninitialized symbol 'rate'
sound/soc/codecs/wcd938x.c:2189 wcd938x_tx_channel_config() error: uninitialized symbol 'reg'.
First one my brining in check to already existing if condition and second one by adding a default switch case to avoid any access to reg.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
