Subject: kbuild: Remove unnecessary 'T' modifier in cmd_ar_builtin_fixup
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a48bd961fb203a7ce68f8110fc53a85f90e24b33;p=thirdparty%2Flinux.git

kbuild: Remove unnecessary 'T' modifier in cmd_ar_builtin_fixup

In cmd_ar_builtin_fixup, the 'T' modifier was added to '$(AR) mPi' to
work around a bug in llvm-ar that caused thin archives to be silently
converted to full archives [1]. Since commit 20c098928356 ("kbuild: Bump
minimum version of LLVM for building the kernel to 15.0.0"), all
supported versions of llvm-ar have this issue fixed, so the 'T' modifier
and comment can be removed.
