If CONFIG_COMMON_CLK is selected then __clk_get and __clk_put are
defined in drivers/clk/clk.c and declared in include/linux/clkdev.h.
Sylwester's series[0] to properly support clk_{get,put} in the common
clock framework made changes to the asm-specific clkdev.h headers, but
not the asm-generic version. Tomeu's recent changes[1] to introduce a
provider/consumer split in the clock framework uncovered this problem,
causing the following build error on any architecture using the
asm-generic clkdev.h (e.g. x86 architecture and the ACPI LPSS driver):
In file included from drivers/acpi/acpi_lpss.c:15:0:
include/linux/clkdev.h:59:5: error: conflicting types for ‘__clk_get’
int __clk_get(struct clk_core *clk);
^
In file included from arch/x86/include/generated/asm/clkdev.h:1:0,
from include/linux/clkdev.h:15,
from drivers/acpi/acpi_lpss.c:15:
include/asm-generic/clkdev.h:20:19: note: previous definition of ‘__clk_get’ was here
static inline int __clk_get(struct clk *clk) { return 1; }
^
Fixed by only declarating __clk_get and __clk_put when
CONFIG_COMMON_CLK is set.
