From: Ivan T. Ivanov Date: Wed, 30 Sep 2015 12:27:00 +0000 (+0300) Subject: tty: serial: msm: Add msm prefix to all driver functions X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=558abdb05fe0c7fc86eba8803d74bc9592c3cb26;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git tty: serial: msm: Add msm prefix to all driver functions Make function naming consistent across this driver. Also rename msm_irq to msm_uart_irq. No functional changes. Signed-off-by: Ivan T.
