If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9127497dea076f4bc8b4a75dac544e5eb1ea3e01 Author: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Date: Thu Aug 11 13:53:05 2022 +0300 mfd: fsl-imx25: Fix check for platform_get_irq() errors [ Upstream commit 75db7907355ca5e2ff606e9dd3e86b6c3a455fe2 ] The mx25_tsadc_remove() function assumes all non-zero returns are success but the platform_get_irq() function returns negative on error and positive non-zero values on success. It never returns zero, but if it did then treat that as a success.
