6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx>
[ Upstream commit b0a4546df24a4f8c59b2d05ae141bd70ceccc386 ]
The SARADCv2 on RK3588 (the only SoC currently supported that has an
SARADCv2) selects the channel through the channel_sel bitfield which is
the 4 lowest bits, therefore the mask should be GENMASK(3, 0) and not
GENMASK(15, 0).
