[ Upstream commit 32b5a2c9950b9284000059d752f7afa164deb15e ]
Commit 715a12334764 ("wireless: don't write C files on failures") drops
the `test -f $$f` check. The list of targets contains the
CONFIG_CFG80211_EXTRA_REGDB_KEYDIR directory itself, and this check used
to filter it out. After the check was removed, the extra keydir option
no longer works, failing with the following message:
od: 'standard input': read error: Is a directory
This commit restores the check to make extra keydir work again.
Fixes: 715a12334764 ("wireless: don't write C files on failures")
