Subject: [PATCH] staging: dgap: tty.c: removes smatch warnings "redundant null
 check"

This patch removes these smatch warnings:
redundant null check on dgap_TmpWriteBuf calling kfree()
redundant null check on brd->SerialDriver->ttys calling kfree()
redundant null check on brd->PrintDriver->ttys calling kfree()

The code checked to see if these variables are null
before freeing. This check isn't needed.
