[PATCH v3 2/2] cpufreq: ti-cpufreq: Use devres managed API in probe()
From: Suman Anna
Date: Thu May 31 2018 - 18:22:23 EST
The ti_cpufreq_probe() function uses regular kzalloc to allocate
the ti_cpufreq_data structure and kfree for freeing this memory
on failures. Simplify this code by using the devres managed
API.
