Matthew Brost f39aaded93 drm/printer: Allow NULL data in devcoredump printer 
[ Upstream commit 53369581dc0c68a5700ed51e1660f44c4b2bb524 ]

We want to determine the size of the devcoredump before writing it out.
To that end, we will run the devcoredump printer with NULL data to get
the size, alloc data based on the generated offset, then run the
devcorecump again with a valid data pointer to print.  This necessitates
not writing data to the data pointer on the initial pass, when it is
NULL.

v5:
 - Better commit message (Jonathan)
 - Add kerenl doc with examples (Jani)
