5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx>
[ Upstream commit 26ce7054d804be73935b9268d6e0ecf2fbbc8aef ]
devm_kasprintf() returns a pointer to dynamically allocated memory.
Pointer could be NULL in case allocation fails. Check pointer validity.
Identified with coccinelle (kmerr.cocci script).
Fixes: 0556f1d580d4 ("media: tvp5150: add input source selection of_graph support")
