Subject: [PATCH v1 2/7] irqchip/alpine-msi: Switch to bitmap_zalloc()
Date:   Fri, 18 Jun 2021 18:16:52 +0300
Message-Id: <20210618151657.65305-2-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 *.
