Subject: [PATCH v11 56/60] PCI: Add debug print out for min_align and alt_size
Date: Thu, 7 Apr 2016 17:16:09 -0700 [thread overview]
Message-ID: <1460074573-7481-57-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1460074573-7481-1-git-send-email-yinghai@kernel.org>
Put all print out for all children align/size and result align/size
together.
We can print out device name at same time with min_align/alt_size
calculation.
So we can shut off debug print out from get_res_add_size() and
get_res_add_align().
