[PATCH -next] spi: bcm-qspi: Fix return value check in bcm_qspi_probe()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

In case of error, the function kcalloc() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Fixes: fa236a7ef240 ("spi: bcm-qspi: Add Broadcom MSPI driver")

Applied "spi: bcm-qspi: Fix return value check in bcm_qspi_probe()" to the spi tree

[Mark Brown]

The patch

   spi: bcm-qspi: Fix return value check in bcm_qspi_probe()

has been applied to the spi tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
