From f3c06cb92f5f05c75e0af1b27cd311706b537009 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 9 Jul 2022 16:10:52 +0200 Subject: [PATCH] PCI: dwc: Use the bitmap API to allocate bitmaps Use devm_bitmap_zalloc() instead of hand-writing them. It is less verbose and it improves the semantic.
