From 1ed9b961be1492e2acc0ce5113936ab08e379de7 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 23 Oct 2021 22:02:05 +0200 Subject: [PATCH] PCI: xgene-msi: Use bitmap_zalloc() when applicable MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 'xgene_msi->bitmap' is a bitmap. So use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.
