ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.
