Subject: [PATCH 4.19 159/229] powerpc/math_emu/efp: Include module.h

From: Nathan Chancellor <nathan@...nel.org>

[ Upstream commit cfe0d370e0788625ce0df3239aad07a2506c1796 ]

When building with a recent version of clang, there are a couple of
errors around the call to module_init():

  arch/powerpc/math-emu/math_efp.c:927:1: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
  module_init(spe_mathemu_init);
  ^
  int
  arch/powerpc/math-emu/math_efp.c:927:13: error: a parameter list without types is only allowed in a function definition
  module_init(spe_mathemu_init);
              ^
  2 errors generated.

module_init() is a macro, which is not getting expanded because module.h
is not included in this file. Add the include so that the macro can
expand properly, clearing up the build failure.
