treewide: Use struct_size() for devm_kmalloc() and friends

2018-06-06T18:15:43+00:00

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);

mmc: cb710: drop free_irq for devm_request_irq allocated irq

2013-09-26T20:55:30+00:00

irq allocated with devm_request_irq should not be freed using
free_irq, because doing so causes a dangling pointer, and a
subsequent double free.

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52+00:00

After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

drivers/misc/cb710: add missing GENERIC_HARDIRQS dependency

2013-02-08T20:23:53+00:00

CB710_CORE (drivers/misc/cb710/core.c) calls devm_request_irq() and
therefore needs a GENERIC_HARDIRQS dependency to prevent a link
error on s390.

PCI: do not call pci_set_power_state with PCI_D3cold

2012-06-23T16:50:44+00:00

PCI subsystem has not been ready for D3cold support yet.  So
PCI_D3cold should not be used as parameter for pci_set_power_state.
This patch is needed for upcoming PCI_D3cold support.

This patch has no functionality change, because pci_set_power_state
will bound the parameter to PCI_D3hot too.
