clocksource/drivers/timer-ti-dm: Fix uninitialized pointer access
Clean-up commit 8c82723414d5 ("clocksource/drivers/timer-ti-dm: Switch to
platform_get_irq") caused a regression where we now try to access
uninitialized data for timer:
drivers/clocksource/timer-ti-dm.c: In function 'omap_dm_timer_probe':
drivers/clocksource/timer-ti-dm.c:798:13: warning: 'timer' may be used
uninitialized in this function [-Wmaybe-uninitialized]
On boot we now get:
Unable to handle kernel NULL pointer dereference at virtual address
00000004
...
(omap_dm_timer_probe) from [<c061ac7c>] (platform_drv_probe+0x48/0x98)
(platform_drv_probe) from [<c0618c04>] (really_probe+0x1dc/0x348)
(really_probe) from [<c0618ef4>] (driver_probe_device+0x5c/0x160)
Let's fix the issue by moving platform_get_irq to happen after timer has
been allocated.
