ieee802154/adf7242: check status of adf7242_read_reg
[ Upstream commit e3914ed6cf44bfe1f169e26241f8314556fd1ac1 ]
Clang static analysis reports this error
adf7242.c:887:6: warning: Assigned value is garbage or undefined
len = len_u8;
^ ~~~~~~
len_u8 is set in
adf7242_read_reg(lp, 0, &len_u8);
When this call fails, len_u8 is not set.
So check the return code.
