Subject: [ALSA] mpu-401: remove MPU401_INFO_UART_ONLY flag
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c1099fcb74ddc005c85beaef33bbe68c9bf3b5bb;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[ALSA] mpu-401: remove MPU401_INFO_UART_ONLY flag

Since the last patch made the ENTER_UART command optional, the
enter_uart option and its corresponding flag have become superfluous.
The uart_enter option remains for backward compatibility but just prints
a warning when used.
