clocksource: efm32: Fix a NULL pointer dereference 2015-03-05T14:01:36+00:00 Yongbae Park yongbae2@gmail.com 2015-03-03T10:46:49+00:00 7b8f10da3bf1056546133c9f54f49ce389fd95ab The initialisation of the efm32 clocksource first sets up the irq and only after that initialises the data needed for irq handling. In case this initialisation is delayed the irq handler would dereference a NULL pointer. I'm not aware of anything that could delay the process in such a way, but it's better to be safe than sorry, so setup the irq only when the clock event device is ready.

clocksource: efm32: use $vendor,$device scheme for compatible string 2014-04-22T09:44:28+00:00 Uwe Kleine-König u.kleine-koenig@pengutronix.de 2014-03-25T14:50:44+00:00 63cc122381bda123c2b1b0137cca09f66e5be660 Wolfram Sang pointed out that "efm32,$device" is non-standard. So use the common scheme and prefix device with "efm32-". The old compatible string is left in place until arch/arm/boot/dts/efm32* is fixed.
