Subject: serial: 8250_uniphier: fix clearing divisor latch access bit
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=09065c5f0f1ff4bfb309975e182b746989a869c5;p=linux-beck.git

serial: 8250_uniphier: fix clearing divisor latch access bit

At this point, 'value' is always a byte, then this code is clearing
bit 15, which is already clear.  I meant to clear bit 7.
