mmc: sdhci-of-arasan: Remove uninitialized ret variables
Clang warns:
drivers/mmc/host/sdhci-of-arasan.c:784:9: warning: variable 'ret' is
uninitialized when used here [-Wuninitialized]
return ret;
^~~
drivers/mmc/host/sdhci-of-arasan.c:738:9: note: initialize the variable
'ret' to silence this warning
int ret;
^
= 0
drivers/mmc/host/sdhci-of-arasan.c:860:9: warning: variable 'ret' is
uninitialized when used here [-Wuninitialized]
return ret;
^~~
drivers/mmc/host/sdhci-of-arasan.c:810:9: note: initialize the variable
'ret' to silence this warning
int ret;
^
= 0
2 warnings generated.
This looks like a copy paste error. Neither function has handling that
needs ret so just remove it and return 0 directly.
