Subject: accel/ivpu: Add test mode flag for disabling timeouts
X-Git-Tag: v6.11-rc1~141^2~21^2~24
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3f440e0b4852288268df4f0757c53ad3031df80c;p=thirdparty%2Fkernel%2Flinux.git

accel/ivpu: Add test mode flag for disabling timeouts

Add new test mode flag that will disable all timeouts
defined in timeout fields of struct ivpu_device.
Remove also reschedule_suspend field as it is unused.
