Subject: Applied "spi: Use kcalloc() in spi_register_board_info()" to the spi tree
Date: Tue, 17 Jan 2017 18:46:17 +0000	[thread overview]
Message-ID: <E1cTYlt-0000U1-Ig@debutante> (raw)
In-Reply-To: <26b9015b-7ba2-3e26-5075-9a78f3884392-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>
The patch
   spi: Use kcalloc() in spi_register_board_info()
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

Subject: [PATCH] spi: Use kcalloc() in spi_register_board_info()
A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus reuse the corresponding function "kcalloc".
This issue was detected by using the Coccinelle software.
