Jonathon Hall 052c4ba7a6 drm/i915: Do not match JSL in ehl_combo_pll_div_frac_wa_needed() 
commit e41d769f1a upstream.

Since commit 0c65dc0626 ("drm/i915/jsl: s/JSL/JASPERLAKE for
platform/subplatform defines"), boot freezes on a Jasper Lake tablet
(Librem 11), usually with graphical corruption on the eDP display,
but sometimes just a black screen.  This commit was included in 6.6 and
later.

That commit was intended to refactor EHL and JSL macros, but the change
to ehl_combo_pll_div_frac_wa_needed() started matching JSL incorrectly
when it was only intended to match EHL.

It replaced:
	return ((IS_PLATFORM(i915, INTEL_ELKHARTLAKE) &&
		 IS_JSL_EHL_DISPLAY_STEP(i915, STEP_B0, STEP_FOREVER)) ||
with:
	return (((IS_ELKHARTLAKE(i915) || IS_JASPERLAKE(i915)) &&
		 IS_DISPLAY_STEP(i915, STEP_B0, STEP_FOREVER)) ||

Remove IS_JASPERLAKE() to fix the regression.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
