From 76411a0d97c3b216ce1c987aa4afa7f3789c89d9 Mon Sep 17 00:00:00 2001 From: Rafael David Tinoco Date: Wed, 6 Jun 2018 14:44:24 -0300 Subject: gpio: selftests: gpio-mockup-chardev GPIOHANDLE_REQUEST_OUTPUT fix Following logic from commit: 22f6592b23, GPIOHANDLE_REQUEST_OUTPUT should handle errors same way as GPIOHANDLE_REQUEST_INPUT does, or else the following error occurs: gpio-mockup-chardev: gpio line<0> test flag<0x2> value<0>: No such file or directory despite the real result of gpio_pin_test(), gpio_debugfs_get() and gpiotools_request_linehandle() functions.
