Subject: genirq/msi: Use MSI_DESC_ALL in msi_add_simple_msi_descs()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=befd780253e774ea9388dd8dfad7c627a0aa7e02;p=linux.git

genirq/msi: Use MSI_DESC_ALL in msi_add_simple_msi_descs()

There are no associated MSI descriptors in the requested range when the MSI
descriptor allocation fails. Use MSI_DESC_ALL as the filter which prepares
the next step to get rid of the filter for freeing.
