Subject: [PATCH v1 2/3] Input: gpio-keys - Switch to bitmap_zalloc()
Date: Fri,  1 Jun 2018 11:31:19 +0300	[thread overview]
Message-ID: <20180601083120.40352-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20180601083120.40352-1-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 *.
