Subject: [PATCH] cpufreq: Fix an IS_ERR() vs NULL bug in spear1340_set_cpu_rate()
Date: Fri, 10 Jul 2026 22:34:13 +0300 [thread overview]
Message-ID: <alFJNUllC3JOKv6z@stanley.mountain> (raw)
The clk_get_parent() function doesn't return error pointers, it returns
NULL on error. Update the error checking to match.
Fixes: 420993221175 ("cpufreq: SPEAr: Add CPUFreq driver")
Signed-off-by: Dan Carpenter <error27@gmail.com>
