Subject: [PATCH] media: i2c: tvp5150: check return value of devm_kasprintf()
Git-commit: 26ce7054d804be73935b9268d6e0ecf2fbbc8aef
Patch-mainline: v6.6-rc1

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).
