6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antoniu Miclaus <antoniu.miclaus@xxxxxxxxxx>
commit 287d998af24326b009ae0956820a3188501b34a0 upstream.
Include the corner cases in the computation of the MIXER_VGATE register
value.
According to the datasheet: The MIXER_VGATE values follows the VCM such
as, that for a 0V to 1.8V VCM, MIXER_VGATE = 23.89 VCM + 81, and for a >
1.8V to 2.6V VCM, MIXER_VGATE = 23.75 VCM + 1.25.
