Subject: [PATCH v6 1/3] regmap: Pass irq_drv_data as a parameter for set_type_config()
Date:   Wed,  5 Apr 2023 11:45:42 -0400
Message-Id: <20e15cd3afae80922b7e0577c7741df86b3390c5.1680708357.git.william.gray@linaro.org>

Allow the struct regmap_irq_chip set_type_config() callback to access
irq_drv_data by passing it as a parameter.

Changes in v6:
 - Wrap lines to 80 characters rather than 100
Changes in v5:
 - Wrap lines to 100 characters rather than 80
Changes in v4: none
Changes in v3:
 - Drop map from set_type_config() parameter list; regmap can be passed
   by irq_drv_data instead
Changes in v2: none
