It can be a problem when a pattern is loaded via the firmware interface.
LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'.
So it should be deleted.


Looks like lp5521_update_program_memory() will be called by
store_engine_load() without holding a lock after this change, is this
correct? I think you need also update store_engine_load() to hold the
lock when calling lp5521_update_program_memory().

Thanks, good point! I've just sent the patch-v2.

Best regards,
Milo
