Re: [PATCH AUTOSEL 5.10 1/6] pm: cpupower: bench: Prevent NULL dereference on malloc failure

Hi!

[ Upstream commit 208baa3ec9043a664d9acfb8174b332e6b17fb69 ]

If malloc returns NULL due to low memory, 'config' pointer can be NULL. Add a check to prevent NULL dereference.

This fixes nothing. We have oom killer, so we don't have malloc returning NULL.

Best regards, Pavel
