bio: Fix outdated comment about bio_alloc_bioset()
In commit 451a9ebf653d28337ba53ed5b4b70b0b9543cca1 bio_alloc_bioset() was refactored not to take NULL as a valid argument for bs. This patch changes the comment for that function accordingly. Currently, passing NULL as argument to parameter bs would result in a NULL pointer dereference. Signed-off-by: Jaak Ristioja <ristioja@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
