Subject: OMAP2/3/4: UART: allow in-order port traversal
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bcf396c48012a5e4c7ab77be5c40df10d6bdb8ad;p=deliverable%2Flinux.git

OMAP2/3/4: UART: allow in-order port traversal

Use list_add_tail() when adding discovered UART ports.  This is so
traversal using list_for_each_entry() will traverse the list in the
order they were found.
