Subject: [PATCH] pinctrl: cherryview: Return correct value if pin in push-pull mode
Git-commit: 5835196a17be5cfdcad0b617f90cf4abe16951a4
Patch-mainline: v6.5-rc1
References: git-fixes
Currently the getter returns ENOTSUPP on pin configured in
the push-pull mode. Fix this by adding the missed switch case.
Fixes: ccdf81d08dbe ("pinctrl: cherryview: add option to set open-drain pin config")
Fixes: 6e08d6bbebeb ("pinctrl: Add Intel Cherryview/Braswell pin controller support")
