Date: Sat, 9 Jul 2022 18:16:46 +0200 From: Christophe JAILLET <christophe.jaillet@...adoo.fr> To: Yang Shen <shenyang39@...wei.com>, Zhou Wang <wangzhou1@...ilicon.com>, Herbert Xu <herbert@...dor.apana.org.au>, "David S. Miller" <davem@...emloft.net> Cc: linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, Christophe JAILLET <christophe.jaillet@...adoo.fr>, linux-crypto@...r.kernel.org Subject: [PATCH] crypto: hisilicon/zip: 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.
