From 12913a78cedc491f89a34ab0b545831d6006fc98 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Wed, 11 May 2016 15:16:12 +0200 Subject: [PATCH] builtin/apply: make gitdiff_verify_name() return void As the value returned by gitdiff_verify_name() is put into the same variable that is passed as a parameter to this function, it is simpler to pass the address of the variable and have gitdiff_verify_name() change the variable itself. This also makes it possible to later have this function return -1 instead of die()ing in case of error.
