* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.

Heiner Kallweit authored
Introduce managed versions of both functions. They allows to simplify the error path in the probe function of rc drivers, and usually also to simplify the remove function. New element managed_alloc in struct rc_dev is needed to correctly handle mixed use, e.g. managed version of rc_register_device and normal version of rc_allocate_device. In addition devm_rc_allocate_device sets rc->dev.parent as having a reference to the parent device might be useful for future extensions. Signed-off-by:
