Subject: [PATCH v17 11/14] thermal: intel: intel_soc_dts_iosf: Utilize for_each_set_clump8 macro
Date: Wed, 9 Oct 2019 11:27:09 -0400 [thread overview]
Message-ID: <335f1ce6411902dbe492a6b2a51fe479dd0f48a5.1570633189.git.vilhelm.gray@gmail.com> (raw)
In-Reply-To: <cover.1570633189.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.
