Subject: [PATCH v1 3/7] irqchip/gic-v2m: Switch to bitmap_zalloc()
Date: Fri, 18 Jun 2021 18:16:53 +0300	[thread overview]
Message-ID: <20210618151657.65305-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210618151657.65305-1-andriy.shevchenko@linux.intel.com>

Switch to bitmap_zalloc() to show clearly what we are allocating.
Besides that it returns pointer of bitmap type instead of opaque void *.
