6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhang Lixu <lixu.zhang@xxxxxxxxx>
[ Upstream commit 92826905ae340b7f2b25759a06c8c60bfc476b9f ]
The variable dev->devc in ish_dev_init was utilized by dev_err before it
was properly assigned. To rectify this, the assignment of dev->devc has
been moved to immediately follow memory allocation.
Without this change "(NULL device *)" is printed for device information.
Fixes: 8ae2f2b0a284 ("HID: intel-ish-hid: ipc: Fix potential use-after-free in work function")
Fixes: ae02e5d40d5f ("HID: intel-ish-hid: ipc layer")
