From 888b245964ad3617866d6d4b5bb8a154a410ef32 Mon Sep 17 00:00:00 2001 From: Hugo Villeneuve Date: Fri, 10 Apr 2026 11:20:10 -0400 Subject: [PATCH] serial: apbuart: remove check for zero baud rate from uart_get_baud_rate() The minimum baud rate supported by this driver is 0, so even for the B0 case, uart_get_baud_rate() will return 9600, not zero. This check predates commit 16ae2a877bf4 ("serial: Fix crash if the minimum rate of the device is > 9600 baud") and is no longer necessary so remove it.
