Staging: bcm: Check correct user provided length and fix error code returned
bcm driver copies a buffer length provided by userpace without checking it.
RxCntrlMsgBitMask is of type unsigned long so only makes sense to copy
sizeof(unsigned long) bytes.
Also, copy_from_user() returns the number of bytes that could not be copied.
The driver is returning that value as error code instead of -EFAULT.
This patch solves both issues.
