From ef578906d849bf05d04d246e9e3994146dddc01d Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Tue, 26 Sep 2017 09:48:37 +0200 Subject: [PATCH] broadcom/vc4: Fix infinite retry in vc4_bo_alloc() cleared_and_retried is always reset to false when jumping to the retry label, thus leading to an infinite retry loop. Fix that by moving the cleared_and_retried variable definitions at the beginning of the function. While we're at it, move the create variable with the other local variables and explicitly reset its content in the retry path.
