From 4f48c30312b7af5365878ab191bb41e7b899e09b Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Mon, 5 Jun 2023 12:51:16 -0700 Subject: [PATCH] pds_core: Fix FW recovery detection Commit 523847df1b37 ("pds_core: add devcmd device interfaces") included initial support for FW recovery detection. Unfortunately, the ordering in pdsc_is_fw_good() was incorrect, which was causing FW recovery to be undetected by the driver. Fix this by making sure to update the cached fw_status by calling pdsc_is_fw_running() before setting the local FW gen.
