Subject: [PATCH] RDMA/qib: Use the bitmap API to allocate bitmaps
Date:   Fri,  8 Jul 2022 19:20:39 +0200
Message-Id: <f7a8588447679e80a438b6188b0603c1a11ad877.1657300671.git.christophe.jaillet@wanadoo.fr>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them.

It is less verbose and it improves the semantic.
