[PATCH 4.14 047/204] pinctrl: cherryview: Return correct value if pin in push-pull mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

[ Upstream commit 5835196a17be5cfdcad0b617f90cf4abe16951a4 ]

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")
