[Impact]

JSL i915 PCI ID has been in 5.10 in commit 651cc835d5f6 ("drm/i915: Add
new EHL/JSL PCI ids"), but it is still marked require_force_probe in
commit 24ea098b7c0d ("drm/i915/jsl: Split EHL/JSL platform info and PCI
ids"), and that's still the case in current drm-intel/drm-intel-next
HEAD. Therefore early phase board for assessment board takes an extra
i915.force_probe=4e71 boot parameter to enable i915.

[Fix]

Intel should remove this flag sometime later when JSL drm is stable
enough. But before that, we can simply remove that flag from jsl_info in
drivers/gpu/drm/i915/i915_pci.c.

[Test Case]

i915 should be loaded with patched kernel, so do:

  $ lsmod|grep i915
  i915

[Where problems could occur]

While this is still an alpha platform in development in OEM projects,
this should not introduce trouble for others. As for JSL, troubles are
expected and to be resolved.
