Subject: [PATCH AUTOSEL 5.10 10/26] ARM: OMAP1: clock: Fix UART rate reporting algorithm
Date: Wed, 1 Jun 2022 09:57:43 -0400 [thread overview]
Message-ID: <20220601135759.2004435-10-sashal@kernel.org> (raw)
In-Reply-To: <20220601135759.2004435-1-sashal@kernel.org>
From: Janusz Krzysztofik <jmkrzyszt@gmail.com>
[ 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.
