Subject: efi_stub: Fix GDT_NOTSYS check
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=14d61d4e577c57ba77b826c6cc9d99a0b3f3fc37;p=u-boot.git

efi_stub: Fix GDT_NOTSYS check

The get_codeseg32() wants to know if a passed in descriptor has
flag GDT_NOTSYS set (desc & GDT_NOTSYS), not whether desc and
GDT_NOTSYS are not != 0 (desk && GDT_NOTSYS).

This is an obvious typo. Fix it up.
