Kees Cook 0ed2dd03b9 treewide: Use struct_size() for devm_kmalloc() and friends 
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);

Danilo Krummrich 1d66af8190 clk: bcm2835: remove remains from stub clk driver 
This commit removes the fixed clocks introduced as a stub clock driver
added with commit 75fabc3f64 ("ARM: bcm2835: add stub clock driver").
Originally they were used to drive the AMBA bus and PL011 uart driver.
Now these clocks are derived by the CPRMAN clock driver and configured
in DT.

Additionally, get rid of init_machine function in bcm2835 board file
as there's nothing to do any longer.

Stephen Boyd b19f009d45 clk: bcm2835: Migrate to clk_hw based registration and OF APIs 
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.

Vladimir Zapolskiy 4d3ac66624 clk: bcm2835: fix check of error code returned by devm_ioremap_resource() 
The change fixes potential oops while accessing iomem on invalid
address, if devm_ioremap_resource() fails due to some reason.

The devm_ioremap_resource() function returns ERR_PTR() and never
returns NULL, which makes useless a following check for NULL.

Eric Anholt 5e63dcc74b clk: bcm2835: Add a driver for the auxiliary peripheral clock gates. 
There are a pair of SPI masters and a mini UART that were last minute
additions.  As a result, they didn't get integrated in the same way as
the other gates off of the VPU clock in CPRMAN.
