Subject: [PATCH v2 4/5] iio: pressure: bmp280: Drop unneeded explicit castings
Date: Mon, 23 Mar 2020 12:41:28 +0200 [thread overview]
Message-ID: <20200323104129.60466-4-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200323104129.60466-1-andriy.shevchenko@linux.intel.com>
In few places the unnecessary explicit castings are being used.
Drop them for good.
