Subject: [PATCH] firmware: arm_scmi: Use the bitmap API to allocate bitmaps
Date:   Fri,  8 Jul 2022 21:30:01 +0200
Message-Id: <c073b1607ada34d5bde6ce1009179cf15bbf0da3.1657308593.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use devm_bitmap_zalloc() instead of hand-writing them.

It is less verbose and it improves the semantic.
