SubjectRe: [PATCH 1/2] rtc-rv8803: fix writing back ctrl in flag register
Hi Alexandre, Alessandro,

the other patch was proved to be unneeded, but this one is still a valid
fix as far as I can understand the code (reusing RV8803_CTRL value to
write into RV8803_FLAG does not look correct)

(I'm also convinced either mostly work because the original values are
usually close enough, but that's not a reason to keep using the wrong
one)


Would you have time to take a look?


Thanks!
