Subject: ASoC: wm8960: Fix WM8960_SYSCLK_PLL mode
From: Stuart Henderson <stuart.henderson@xxxxxxxxxx>
commit 6bb7451429084cefcb3a18fff809f7992595d2af upstream.
With the introduction of WM8960_SYSCLK_AUTO mode, WM8960_SYSCLK_PLL mode was
made unusable. Ensure we're not PLL mode before trying to use MCLK.
Fixes: 3176bf2d7ccd ("ASoC: wm8960: update pll and clock setting function")
