Subject: [PATCH 3/3] platform/x86: dell-laptop: Parse the charge end threshold as an int
Date: Fri, 13 Nov 2026 22:29:27 -0800	[thread overview]
Message-ID: <29edd5de9d2d7f90adfd5f9c889e50ad032d2d9c.1794633179.git.rosenp@gmail.com> (raw)
In-Reply-To: <cover.1794633179.git.rosenp@gmail.com>

charge_control_end_threshold_store() passes a pointer to an int to
kstrtouint(), which only builds because the kernel disables
-Wpointer-sign, and makes the following "end < 0" check dead code.
Use kstrtoint() like charge_control_start_threshold_store(). Values
outside 0 to 100 are rejected either way.
