[PATCH 5.10 0/1] staging: rtl8192u: Add null check in rtl8192_usb_initendpoints

[Danila Chernetsov <listdansp@xxxxxxx>]

SVACE reports return value of a function 'usb_alloc_urb' is dereferenced
 without checking for null in 5.10 stable releases.
The problem has been fixed by the following 
patch which can be cleanly applied to the 5.10 branch.
