device/testing/linux-samsung-milletwifi/0001-Fix-signature-mismatch-for-msm_pm_boot_init.patch

+From 8722cd082aff5d3afae4ea7f7d631dd76d616aff Mon Sep 17 00:00:00 2001
+From: bjorn3 <17426603+bjorn3@users.noreply.github.com>
+Date: Wed, 22 Jun 2022 13:01:01 +0200
+Subject: [PATCH] Fix signature mismatch for msm_pm_boot_init
+
+This previously caused msm_pm_boot_init to incorrectly get handled as
+__init function when it needs to be an __devinit function as it is
+called by msm_pm_boot_probe, which is an __devinit function.
