mfd: twl-core: Fix chip ID for the twl6030-pwm module
The correct chip id is 1 since the PWM module is on address 0x49. With the current TWL6030_MODULE_ID1 the kernel will crash early since we have: #define TWL6030_MODULE_ID1 0x0E and static struct twl_client twl_modules[4]; Down in the stack we try to get the module by: struct twl_client *twl = &twl_modules[chip]; Which is obviously going to do nasty things.
