From 2e1bfb314c99de2f7b9c8280408316ad2f316de9 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Mon, 4 Jul 2022 22:31:51 +0200 Subject: [PATCH] gpu: host1x: Use the bitmap API to allocate bitmaps Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic. While at it, remove a useless bitmap_zero() call. The bitmap is already zero'ed when allocated.
