From 5466491c9e3309ed5c7adbb8fad6e93fcc9a8fe9 Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Mon, 9 Jun 2025 14:28:27 -0700 Subject: [PATCH] ionic: Prevent driver/fw getting out of sync on devcmd(s) Some stress/negative firmware testing around devcmd(s) returning EAGAIN found that the done bit could get out of sync in the firmware when it wasn't cleared in a retry case. While here, change the type of the local done variable to a bool to match the return type from ionic_dev_cmd_done().
