From: Kevin Hilman Date: Wed, 8 May 2013 23:48:01 +0000 (-0700) Subject: ARM: OMAP2+: omap_device: use late_initcall_sync X-Git-Tag: omap-for-v3.10/fixes-for-merge-window-part2~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e7e17c538604928b98107a08c2c5dc54745d85fe;p=pandora-kernel.git ARM: OMAP2+: omap_device: use late_initcall_sync If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled as a module, the kernel boot hangs early as the clocks for serial port are cut while earlyprintk still uses the port. The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.
