Subject: drm/panfrost: Prefix interrupt handlers' names
Git-commit: 73896f60d4865657740c64821a7b18825a9bf96c
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Currently, the interrupt lines requested by Panfrost
use unmeaningful names, which adds some obscurity
to interrupt introspection (i.e. any tool based
on procfs' interrupts file).
In order to improve this, prefix each requested
interrupt with the module name: panfrost-{gpu,job,mmu}.
