A previous version of the series is [0] and this addresses issues pointed out by Stephen Boyd. This series is composed of the following patches: Javier Martinez Canillas (3): clk: Don't dereference parent clock if is NULL clk: Add __clk_hw_set_clk helper function clk: Replace explicit clk assignment with __clk_hw_set_clk drivers/clk/clk-composite.c | 20 ++++++++++---------- drivers/clk/clk.c | 4 ++-- drivers/clk/pxa/clk-pxa.c | 2 +- drivers/clk/st/clk-flexgen.c | 20 ++++++++++---------- drivers/clk/st/clkgen-mux.c | 14 +++++++------- drivers/clk/tegra/clk-periph.c | 14 +++++++------- include/linux/clk-provider.h | 6 ++++++ 7 files changed, 43 insertions(+), 37 deletions(-) Best regards, Javier [0]: https://lkml.org/lkml/2015/2/11/139 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
