Subject: PCI: Use msix_table_size() directly, drop multi_msix_capable()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=527eee292d2ee69708a20b90049ef49bdeefc882;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: Use msix_table_size() directly, drop multi_msix_capable()

The users of multi_msix_capable() are really interested in the table
size, so just say what we mean.
