Subject: [PATCH v12 10/11] thermal: intel: intel_soc_dts_iosf: Utilize for_each_set_clump8 macro
Date: Mon, 25 Mar 2019 15:26:00 +0900	[thread overview]
Message-ID: <c21e479a7aa31c5464310c19e6c97c994e07a622.1553494625.git.vilhelm.gray@gmail.com> (raw)
In-Reply-To: <cover.1553494625.git.vilhelm.gray@gmail.com>

Utilize for_each_set_clump8 macro, and the bitmap_set_value8 and
bitmap_get_value8 functions, where appropriate. In addition, remove the
now unnecessary temp_mask and temp_shift members of the
intel_soc_dts_sensor_entry structure.
