Subject: ACPI / processor: Remove redundant NULL check before kfree
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5273a258373a84bbbcbccabb356de5b68e2b8931;p=linux-beck.git

ACPI / processor: Remove redundant NULL check before kfree

kfree() on a NULL pointer is a no-op, so remove a redundant NULL
pointer check in map_mat_entry().
