MIPS: Routerboard 532: Fix vendor retry check code
[ Upstream commit ae9daffd9028f2500c9ac1517e46d4f2b57efb80 ]
read_config_dword() contains strange condition checking ret for a
number of values. The ret variable, however, is always zero because
config_access() never returns anything else. Thus, the retry is always
taken until number of tries is exceeded.
The code looks like it wants to check *val instead of ret to see if the
read gave an error response.
