The patch titled
Be a bit defensive in quirk_nvidia_ck804() so we don't risk dereferencing a NULL pdev.
has been removed from the -mm tree. Its filename was
be-a-bit-defensive-in-quirk_nvidia_ck804-so-we-dont-risk-dereferencing-a-null-pdev.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Be a bit defensive in quirk_nvidia_ck804() so we don't risk dereferencing a NULL pdev.
From: Jesper Juhl <jesper.juhl@xxxxxxxxx>
pci_get_slot() may return NULL if nothing was found. quirk_nvidia_ck804()
does not check the value returned from pci_get_slot(), so it may end up
causing a NULL pointer deref.
