Subject: [PATCH v7 3/7] thermal/drivers/exynos: Remove redundant IS_ERR() checks for clk_sec clock
Date: Wed, 13 Aug 2025 18:39:47 +0530	[thread overview]
Message-ID: <20250813131007.343402-4-linux.amoon@gmail.com> (raw)
In-Reply-To: <20250813131007.343402-1-linux.amoon@gmail.com>

Remove unnecessary IS_ERR() checks for the clk_sec clock,
the clk_enable() and clk_disable() functions can handle NULL clock
pointers, so the additional checks are redundant and have been removed
to simplify the code.

Reviewed-by: Lukasz Luba <lukasz.luba@arm.com>
Signed-off-by: Anand Moon <linux.amoon@gmail.com>
---
v7: None
v6: Add Rb - Lukasz and Fix the typo in the subject
v5: None
v4: drop IE_ERR() for clk_unprepare() as its handle in earlier code.
v3: improve the commit message.
