The format of your commit is wrong. You should make the commit message
look like this in git:
net: wan: Add checks for NULL
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.

v2: Add check for NULL for unmap_si_regs
But the first line (subject) is still not specific enough.
Refer to the bug that's being fixed, not how it's fixed.
Also no braces needed around single-line if blocks.
