regmap: fix a NULL pointer dereference in __regmap_init __regmap_init() may receive a NULL `struct regmap_bus *bus' pointer, for example, from snd_hdac_regmap_init(), and it make sure that it does not NULL deference `bus`, except around ->max_raw_read and ->max_raw_write initialisation. Add missing check. Signed-off-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
