Smatch reported issue in Rockchip video

[Andrew Goodbody]

Smatch reports the following issue

drivers/video/rockchip/rk_edp.c:769 rk_edp_i2c_read() warn: ignoring 
unreachable code.

Looking at the code, the warning is true, there is some code there that 
is unreachable. It is not clear to me what the fix for this should be 
but I will prepare a patch if someone could suggest what needs to be done.
