bus_type a const *"), the driver core can properly handle constant
struct bus_type, move the fsl_mc_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be

Add a null pointer check, and release 'ent' to avoid memory leaks.

Sure,i'll follow your suggestion in v3 patch:
1. set new to NULL
2. add a 'if' judgment before 'kmem_cache_create'

Thanks for your reply.

I will update v2 patch with "panic".
Thanks again,
