Subject: [PATCH] gpio: sim: check the label length when setting up device properties
Date: Thu, 20 Jan 2022 20:49:48 +0100 [thread overview]
Message-ID: <20220120194948.1138813-1-brgl@bgdev.pl> (raw)
If the user-space sets the chip label to an empty string - we should
check the length and assign the default name or otherwise line hogs
will not be properly attached.
Fixes: cb8c474e79be ("gpio: sim: new testing module")
