Subject: sh: pfc: Ignore pinmux GPIOs with invalid enum IDs.
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=e3e79454a7c81a5e48c6d6b31068b12936e7d780;p=~shefty%2Frdma-dev.git

sh: pfc: Ignore pinmux GPIOs with invalid enum IDs.

If we encounter invalid entries in the pinmux GPIO range, make sure we've
still got a dummy pin definition but don't otherwise map it.
