2014-05-06	spi: efm32: use $vendor,$device scheme for compatible string	Uwe Kleine-König
	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.

2013-10-09	spi: efm32: drop unused struct and fix size check	Uwe Kleine-König
	The variable efm32_spi_pdata_default origins from an earlier revision of the patch introducing the driver, its use was dropped because of review comments but I forgot to also drop the variable itself.

	This call is needed to cleanup the resources requested by spi_bitbang_start in the probe callback. Noticed-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-10-07	spi: bitbang: Let spi_bitbang_start() take a reference to master	Axel Lin
	Many drivers that use bitbang library have a leak on probe error paths. This is because once a spi_master_get() call succeeds, we need an additional spi_master_put() call to free the memory. Fix this issue by moving the code taking a reference to master to spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on success. With this change, the caller is responsible for calling spi_bitbang_stop() to decrement the reference and spi_master_put() as counterpart of spi_alloc_master() to prevent a memory leak. So now we have below patten for drivers using bitbang library: probe: spi_alloc_master -> Init reference count to 1 spi_bitbang_start -> Increment reference count remove: spi_bitbang_stop -> Decrement reference count spi_master_put -> Decrement reference count (reference count reaches 0) Fixup all users accordingly.

2013-09-23	spi: efm32: Don't call kfree() after spi_master_put()	Axel Lin
	Calling kfree() to clean up the memory obtained from spi_alloc_master() is wrong as this is done in spi_master_release() when spi_master->dev's refcount reaches zero. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
