Esina Ekaterina 95347e41ca net: wan: Add checks for NULL for utdm in undo_uhdlc_init and unmap_si_regs
[ Upstream commit 488e0bf7f3 ]

If uhdlc_priv_tsa != 1 then utdm is not initialized.
And if ret != NULL then goto undo_uhdlc_init, where
utdm is dereferenced. Same if dev == NULL.

Found by Astra Linux on behalf of Linux Verification Center
(linuxtesting.org) with SVACE.
