ASoC: codecs: msm8916-wcd-analog: always true condition
Static checkers complain that unsigned int val is always >= 0. The context is that snd_soc_read() returns -1U on error. This is harmless because we're checking that CDC_A_MBHC_RESULT_1_BTN_RESULT_MASK is not set, and it will always be set for -1U. I could have just removed the check against -1 but I preserved it because I thought it helped with readability.
