Subject: [PATCH] crypto: qat - replace disable_vf2pf_interrupts()
Git-commit: e3e668fc77153591553a14c4077c619b2ab55974
Patch-mainline: v5.19-rc1
References: jsc#PED-1073
As a consequence of the refactored VF2PF interrupt handling logic, a
function that disables specific VF2PF interrupts is no longer needed.
Instead, a simpler function that disables all the interrupts, also
hiding the device specific amount of VFs to be disabled from the
pfvf_ops users, would be sufficient.
This patch replaces disable_vf2pf_interrupts() with the new
disable_all_vf2pf_interrupts(), which doesn't need any argument and
disables all the VF2PF interrupts.
