Date: Sat, 23 Oct 2021 21:24:22 +0200 From: Christophe JAILLET <christophe.jaillet@...adoo.fr> To: mathieu.poirier@...aro.org, suzuki.poulose@....com, mike.leach@...aro.org, leo.yan@...aro.org, alexander.shishkin@...ux.intel.com, mcoquelin.stm32@...il.com, alexandre.torgue@...s.st.com Cc: coresight@...ts.linaro.org, linux-arm-kernel@...ts.infradead.org, linux-stm32@...md-mailman.stormreply.com, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, Christophe JAILLET <christophe.jaillet@...adoo.fr> Subject: [PATCH] coresight: Use devm_bitmap_zalloc when applicable 'drvdata->chs.guaranteed' is a bitmap. So use 'devm_bitmap_kzalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments.
