From: Jiri Slaby (SUSE) Date: Mon, 5 Aug 2024 10:20:37 +0000 (+0200) Subject: serial: remove quot_frac from serial8250_do_set_divisor() X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=259b46204885431f2853afa2a2bffa63f3705e67;p=users%2Fjedix%2Flinux-maple.git serial: remove quot_frac from serial8250_do_set_divisor() quot_frac is unused in serial8250_do_set_divisor() since commit b2b4b8ed3c06 (serial: 8250_exar: Move custom divisor support out from 8250_port). So no point to pass it.
