From be4a1326d12cce8df1f57017bf4112eaab437a38 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Wed, 9 Dec 2015 14:50:26 -0800 Subject: [PATCH] test: firmware_class: use kstrndup() where appropriate We're essentially just doing an open-coded kstrndup(). The only differences are with what happens after the first '\0' character, but request_firmware() doesn't care about that.
