Subject: serial: meson: fix setting number of stop bits
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=88f37d707132fa7854d337455e3290af1c8fae5d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: meson: fix setting number of stop bits

The stop bit value as to be or'ed, so far this worked only just by chance
because AML_UART_STOP_BIN_1SB is 0.
