6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Helge Deller <deller@xxxxxx>
commit c8708d758e715c3824a73bf0cda97292b52be44d upstream.
Printing the inventory on a serial console can be quite slow and thus may
trigger the hung task detector (CONFIG_DETECT_HUNG_TASK=y) and possibly
reboot the machine. Adding a cond_resched() prevents this.
