Subject: mm: pgtable: change pt parameter of tlb_remove_ptdesc() to struct ptdesc*
X-Git-Tag: v6.15-rc1~38^2~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a03c275a3ad4e47d479a63037b72f2b305f0c13;p=thirdparty%2Fkernel%2Flinux.git

mm: pgtable: change pt parameter of tlb_remove_ptdesc() to struct ptdesc*

All callers of tlb_remove_ptdesc() pass it a pointer of struct ptdesc, so
let's change the pt parameter from void * to struct ptdesc * to perform a
type safety check.
