Subject: serial: omap: optimization with section annotations
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6d608ef351bbd0b49427b5b6c6ec6d7622bc0d22;p=openwrt%2Fstaging%2Fblogic.git

serial: omap: optimization with section annotations

Two functions:
omap_serial_fill_features_erratas() and
of_get_uart_port_info() are only called from probe().
Marking them as __devinit gives us another
oportunity to free some code after .init.text
is done.
