Subject: [PATCH 1/2] rtc-rv8803: fix writing back ctrl in flag register
Date: Mon, 1 Nov 2021 10:33:59 +0900 [thread overview]
Message-ID: <20211101013400.325855-1-dominique.martinet@atmark-techno.com> (raw)
ctrl is set from read_regs(..FLAG, 2, ctrl), so ctrl[0] is FLAG
and ctrl[1] is the CTRL register.
Use ctrl[0] to write back to the FLAG register as appropriate.

This probably works in practice because the two registers are pretty close,
but might as well fix it and use the correct register.
