Subject: [PATCH] staging: mt7621-pci: don't return if get gpio fails
|
|
|
|
In some platforms gpio's are not used for reset but
|
|
for other purposes. Because of that when we try to
|
|
get them are valid gpio's but are already assigned
|
|
to do other function. To avoid those kind of problems
|
|
in those platforms just notice the fail in the kernel
|
|
but continue doing normal boot.
