From: Bartosz Golaszewski Date: Thu, 8 Nov 2018 16:52:53 +0000 (+0100) Subject: gpio: mockup: fix indicated direction X-Git-Tag: rel_imx_4.19.35_1.1.0~8021 X-Git-Url: https://git.somdevices.com/?a=commitdiff_plain;h=b8c51924b4e1bc019a81aae3d6456ac26310cd38;p=linux.git gpio: mockup: fix indicated direction [ Upstream commit bff466bac59994cfcceabe4d0be5fdc1c20cd5b8 ] Commit 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning") fixed an existing issue but broke libgpiod tests by changing the default direction of dummy lines to output. We don't break user-space so make gpio-mockup behave as before.
