From c205edcd86dac01c205e4eadf6d0d95965e7a566 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 12 Apr 2024 20:39:37 +0300 Subject: [PATCH] serial: 8250_dw: Hide a cast in dw8250_serial_inq() dw8250_serial_inq() uses unsigned int variable to store 8-bit value. Due to that it needs a cast which can be avoided by switching to use u8 instead of unsigned int.
