Subject: [PATCH v12 2/9] cpufreq: simplify boolean parsing with kstrtobool in store function
Date: Wed, 19 Jun 2024 17:16:35 +0800	[thread overview]
Message-ID: <26f6ce59390a157cf37c622dd2fcf14b5738a8cf.1718787627.git.perry.yuan@amd.com> (raw)
In-Reply-To: <cover.1718787627.git.perry.yuan@amd.com>

Update the cpufreq store function to use kstrtobool for parsing boolean
values. This simplifies the code and improves readability by using a
standard kernel function for boolean string conversion.
