From 5afdd990ce2ea178eb6cbd31b197cc3d12a675bf Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Wed, 20 Jul 2022 20:13:54 +0200 Subject: scsi: hpsa: 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.
