From f87ba66a2a1b2e1dc1c4ece51fa5db93c9cf1d43 Mon Sep 17 00:00:00 2001 From: Ruan Jinjie Date: Fri, 4 Aug 2023 17:32:50 +0800 Subject: [PATCH] USB: misc: Remove unnecessary NULL values The NULL initialization of the pointers assigned by kzalloc() first is not necessary, because if the kzalloc() failed, the pointers will be assigned NULL, otherwise it works as usual. so remove it.
