From 0fec518018cc5ceffa706370b6e3acbbb1e3c798 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Tue, 2 Aug 2022 13:23:09 -0700 Subject: [PATCH] tty: serial: qcom-geni-serial: Fix %lu -> %u in print statements When we multiply an unsigned int by a u32 we still end up with an unsigned int. That means we should specify "%u" not "%lu" in the format code. NOTE: this fix was chosen instead of somehow promoting the value to "unsigned long" since the max baud rate from the earlier call to uart_get_baud_rate() is 4000000 and the max sampling rate is 32. 4000000 * 32 = 0x07a12000, not even close to overflowing 32-bits. Fixes: c474c775716e ("tty: serial: qcom-geni-serial: Fix get_clk_div_rate() which otherwise could return a sub-optimal clock rate.")
