6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: David Lechner <dlechner@xxxxxxxxxxxx> [ Upstream commit 7fe2d05cee46b1c4d9f1efaeab08cc31a0dfff60 ] This fixes a use before initialization in ad2s1210_probe(). The ad2s1210_setup_gpios() function uses st->sdev but it was being called before this field was initialized.
