Subject: [PATCH AUTOSEL 6.1 06/33] selftests: gpio: gpio-sim: Fix BUG: test FAILED due to recent change
Date: Wed, 31 May 2023 09:41:32 -0400 [thread overview]
Message-ID: <20230531134159.3383703-6-sashal@kernel.org> (raw)
In-Reply-To: <20230531134159.3383703-1-sashal@kernel.org>
From: Mirsad Todorovac <mirsad.todorovac@alu.unizg.hr>
[ Upstream commit 976d3c6778e99390c6d854d140b746d12ea18a51 ]
According to Mirsad the gpio-sim.sh test appears to FAIL in a wrong way
due to missing initialisation of shell variables:
4.2. Bias settings work correctly
cat: /sys/devices/platform/gpio-sim.0/gpiochip18/sim_gpio0/value: No such file or directory
./gpio-sim.sh: line 393: test: =: unary operator expected
bias setting does not work
GPIO gpio-sim test FAIL
After this change the test passed:
4.2. Bias settings work correctly
GPIO gpio-sim test PASS
His testing environment is AlmaLinux 8.7 on Lenovo desktop box with
the latest Linux kernel based on v6.2:
Linux 6.2.0-mglru-kmlk-andy-09238-gd2980d8d8265 x86_64
