media: mxl111sf: Fix potential null pointer dereference
Reviewing the delta between cppcheck output of v4.9.39 and v4.9.40 stable updates, I stumbled on the new warning: mxl111sf.c:80: (warning) Possible null pointer dereference: rbuf Since copying state->rcvbuf into rbuf is not needed in the 'write-only' scenario (i.e. calling mxl111sf_ctrl_msg() from mxl111sf_i2c_send_data() or from mxl111sf_write_reg()), bypass memcpy() in this case.
