The kernel has grown a number of different implementations of
DIV_ROUND_CLOSEST_ULL(). That is, a macro that does the same as
DIV_ROUND_CLOSEST() but with the first operand being an unsigned long
long. That means that you have to do the division using do_div()
instead of using the C division operator '/'.
This series move the implementation in
drivers/gpu/drm/i915/intel_drv.h to linux/kernel.h and then removes
the other similar implementations of the same code in
drivers/clk/bcm/clk-kona.h, drivers/cpuidle/governors/menu.c and
drivers/media/dvb-frontends/cxd2820r_priv.h in favor of the one in
kernel.h
Changes since v1:
- inlcude linux/kernel.h in drivers/gpu/drm/i915/intel_panel.c
instead of drivers/gpu/drm/i915/intel_drv.h as Emil Velikov
suggests
- Avoid evaluating 'divisor' twice
Javi Merino (4):
kernel.h: Implement DIV_ROUND_CLOSEST_ULL
clk: bcm/kona: use DIV_ROUND_CLOSEST_ULL()
cpuidle: menu: use DIV_ROUND_CLOSEST_ULL()
media: cxd2820r: use DIV_ROUND_CLOSEST_ULL()
