Subjectlinux-next: build failure after merge of the tty tree
Date
Hi all,

After merging the tty tree, today's linux-next build (x86 allmodconfig)
failed like this:

Caused by commit

c474c775716edd46a5 ("tty: serial: qcom-geni-serial: Fix get_clk_div_rate() which otherwise could return a sub-optimal clock rate.")

I have used the tree from 20220727 instead.
