[PATCH] drm/i915: Remove duplicate inline specifier on write_pte

[PATCH] drm/i915: Remove duplicate inline specifier on write_pte

[Nathan Chancellor]

When building with clang:

 drivers/gpu/drm/i915/gt/gen8_ppgtt.c:392:24: warning: duplicate
 'inline' declaration specifier [-Wduplicate-decl-specifier]
 declaration specifier [-Wduplicate-decl-specifier]
 static __always_inline inline void
                        ^
 include/linux/compiler_types.h:138:16: note: expanded from macro
 'inline'
 #define inline inline __gnu_inline __inline_maybe_unused notrace
                ^
 1 warning generated.

__always_inline is defined as 'inline __attribute__((__always_inline))'
so we do not need to specify it twice.

Fixes: 84eac0c65940 ("drm/i915/gt: Force pte cacheline to main memory")
