5.15-stable review patch. If anyone has any objections, please let me know.

From: Daniel Sneddon daniel.sneddon@linux.intel.com
commit 04f4230e2f86a4e961ea5466eda3db8c1762004d upstream.
The definition of spectre_bhi_state() incorrectly returns a const char * const. This causes the a compiler warning when building with W=1:
warning: type qualifiers ignored on function return type [-Wignored-qualifiers] 2812 | static const char * const spectre_bhi_state(void)
Remove the const qualifier from the pointer.
