From 2d188e3b06ed5db9f1f477388d1551d632e1fd68 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Sun, 10 Apr 2022 15:07:54 +0200 Subject: [PATCH] ARM: OMAP1: clock: Fix UART rate reporting algorithm [ Upstream commit 338d5d476cde853dfd97378d20496baabc2ce3c0 ] Since its introduction to the mainline kernel, omap1_uart_recalc() helper makes incorrect use of clk->enable_bit as a ready to use bitmap mask while it only provides the bit number. Fix it.
