5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx> commit bcdab6f74c91cda19714354fd4e9e3ef3c9a78b3 upstream. This driver makes use of regmap_spi, but does not select the required module. Add the missing 'select REGMAP_SPI'.
