Subject: [PATCH] crypto: qat - move vf2pf interrupt helpers
Git-commit: 08ea97f48883a5d3178e09433b449bafc5f2a314
Patch-mainline: v5.17-rc1
References: jsc#PED-1073
Move vf2pf interrupt enable and disable functions from adf_pf2vf_msg.c
to adf_isr.c
This it to separate the interrupt related code from the PFVF protocol
logic.
With this change, the function adf_disable_vf2pf_interrupts_irq() is
only called from adf_isr.c and it has been marked as static.
