From 2a166929bc0a3ae754365dabc455039fd1be82ca Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Thu, 16 Jun 2022 09:34:35 +0200 Subject: [PATCH] regmap: Wire up regmap_config provided bulk write in missed functions There are some functions that were missed by commit d77e74561368 ("regmap: Add bulk read/write callbacks into regmap_config") when support to define bulk read/write callbacks in regmap_config was introduced. The regmap_bulk_write() and regmap_noinc_write() functions weren't changed to use the added map->write instead of the map->bus->write handler. Also, the regmap_can_raw_write() was not modified to take map->write into account. So will only return true if a bus with a .write callback is set.
