2018-06-06	treewide: Use struct_size() for devm_kmalloc() and friends	Kees Cook	1	-2/+2
	Replaces open-coded struct size calculations with struct_size() for devm_, f2fs_, and sock_* allocations. Automatically generated (and manually adjusted) from the following Coccinelle script: // Direct reference to struct field. @@ identifier alloc =~ "devm_kmalloc\|devm_kzalloc\|sock_kmalloc\|f2fs_kmalloc\|f2fs_kzalloc"; expression HANDLE; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(HANDLE, sizeof(VAR) + COUNT sizeof(VAR->ELEMENT), GFP) + alloc(HANDLE, struct_size(VAR, ELEMENT, COUNT), GFP) // mr = kzalloc(sizeof(mr) + m * sizeof(mr->map[0]), GFP_KERNEL); @@ identifier alloc =~ "devm_kmalloc\|devm_kzalloc\|sock_kmalloc\|f2fs_kmalloc\|f2fs_kzalloc"; expression HANDLE; expression GFP; identifier VAR, ELEMENT; expression COUNT; @@ - alloc(HANDLE, sizeof(VAR) + COUNT sizeof(VAR->ELEMENT[0]), GFP) + alloc(HANDLE, struct_size(VAR, ELEMENT, COUNT), GFP) // Same pattern, but can't trivially locate the trailing element name, // or variable name. @@ identifier alloc =~ "devm_kmalloc\|devm_kzalloc\|sock_kmalloc\|f2fs_kmalloc\|f2fs_kzalloc"; expression HANDLE; expression GFP; expression SOMETHING, COUNT, ELEMENT; @@ - alloc(HANDLE, sizeof(SOMETHING) + COUNT * sizeof(ELEMENT), GFP) + alloc(HANDLE, CHECKME_struct_size(&SOMETHING, ELEMENT, COUNT), GFP) Signed-off-by: Kees Cook <keescook@chromium.org>
2016-11-29	mfd: pm8xxx: add support to pm8821	Srinivas Kandagatla	1	-10/+221
	This patch adds support to PM8821 PMIC and interrupt support. PM8821 is companion device that supplements primary PMIC PM8921 IC. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2016-11-21	mfd: qcom-pm8xxx: Clean up PM8XXX namespace	Linus Walleij	1	-0/+429
	The Kconfig and file naming for the PM8xxx driver is totally confusing: - Kconfig options MFD_PM8XXX and MFD_PM8921_CORE, some in-kernel users depending on or selecting either at random. - A driver file named pm8921-core.c even if it is indeed used by the whole PM8xxx family of chips. - An irqchip named pm8xxx since it was (I guess) realized that the driver was generic for all pm8xxx PMICs. As I may want to add support for PM8901 this is starting to get really messy. Fix this situation by: - Remove the MFD_PM8921_CORE symbol and rely solely on MFD_PM8XXX and convert all users, including LEDs Kconfig and ARM defconfigs for qcom and multi_v7 to use that single symbol. - Renaming the driver to qcom-pm8xxx.c to fit along the two other qcom* prefixed drivers. - Rename functions withing the driver from 8921 to 8xxx to indicate it is generic. - Just drop the =m config from the pxa_defconfig, I have no clue why it is even there, it is not a Qualcomm platform. (Possibly older Kconfig noise from saveconfig.)
