This change added a kernel-doc warning:

drivers/pci/endpoint/functions/pci-epf-vntb.c:658: warning: Function parameter or member 'num_mws' not described in 'epf_ntb_mw_bar_clear'

Can you fix this, please?

I use this to check for kernel-doc warnings:

$ find drivers/pci -type f -name \*.[ch] | xargs scripts/kernel-doc -none
