Nesting container_of() causes warnings with W=2, which is annoying if it happens in headers and fills the build log like: In file included from drivers/clk/qcom/clk-alpha-pll.c:6: drivers/clk/qcom/clk-alpha-pll.c: In function 'clk_alpha_pll_hwfsm_enable': include/linux/kernel.h:852:8: warning: declaration of '__mptr' shadows a previous local [-Wshadow] 852 | void *__mptr = (void *)(ptr); \ | ^~~~~~ drivers/clk/qcom/clk-alpha-pll.c:155:31: note: in expansion of macro 'container_of' 155 | #define to_clk_alpha_pll(_hw) container_of(to_clk_regmap(_hw), \ | ^~~~~~~~~~~~ drivers/clk/qcom/clk-regmap.h:27:28: note: in expansion of macro 'container_of' 27 | #define to_clk_regmap(_hw) container_of(_hw, struct clk_regmap, hw) | ^~~~~~~~~~~~ drivers/clk/qcom/clk-alpha-pll.c:155:44: note: in expansion of macro 'to_clk_regmap' 155 | #define to_clk_alpha_pll(_hw) container_of(to_clk_regmap(_hw), \ | ^~~~~~~~~~~~~ drivers/clk/qcom/clk-alpha-pll.c:254:30: note: in expansion of macro 'to_clk_alpha_pll' 254 | struct clk_alpha_pll *pll = to_clk_alpha_pll(hw); | ^~~~~~~~~~~~~~~~ include/linux/kernel.h:852:8: note: shadowed declaration is here 852 | void *__mptr = (void *)(ptr); \ | ^~~~~~ Redefine two copies of the to_clk_regmap() macro as inline functions to avoid a lot of these.
