[PATCH 3.12 028/182] spi: efm32: use $vendor,$device scheme for compatible string

[Jiri Slaby]

From: Uwe Kleine-KÃnig <u.kleine-koenig@xxxxxxxxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 12f6dd860cf8bf036c0bec38c00a53da71bcd43a upstream.

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.
