Subject: [PATCH 1/2] firmware: ti_sci: Use the bitmap API to allocate bitmaps
Date:   Fri,  8 Jul 2022 21:23:46 +0200
Message-Id: <3ee11e9e83f7c1552d237f5c28f554319fcbbf1f.1657308216.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.
