Subject: serial: apbuart: Fixup apbuart_console_init()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=568389c257fa7d74ce36c2f78bad31965fded4cf;p=linux-beck.git

serial: apbuart: Fixup apbuart_console_init()

commit 35c64e5d (drivers: serial: apbuart: Handle OF failures
gracefully) missed that the modified grlib_apbuart_configure()
function is called from apbuart_console_init() as well.

Fix the fallout.
