Subject: [PATCH] clk: mediatek: fix cppcheck error for uninitialized variable
Date: Mon, 25 Dec 2023 20:58:04 +0530	[thread overview]
Message-ID: <20231225152806.3716898-1-user@falcon> (raw)

From: Kishan Dudhatra <kishan.dudhatra@siliconsignals.io>

cppcheck reports below warning

clk/mediatek/clk-fhctl.c:206:27:
error: Uninitialized variable: pll_postdiv [uninitvar]
if (postdiv && postdiv < pll_postdiv)

This is due to uninitialization of variable pll_postdiv,
which is now initialized as part of this patch.

Signed-off-by: Kishan Dudhatra <kishan.dudhatra@siliconsignals.io>
