What's the difference between RPM_SMD_LN_BB_CLK and RPM_SMD_BB_CLK1?
$ git grep RPM_SMD_LN_BB_CLK
arch/arm64/boot/dts/qcom/msm8996.dtsi: clocks = <&rpmcc RPM_SMD_LN_BB_CLK>,

$ git grep 'RPM_SMD_BB_CLK1\>'
Documentation/devicetree/bindings/sound/qcom,wcd9335.txt: <&rpmcc RPM_SMD_BB_CLK1>;
drivers/clk/qcom/clk-smd-rpm.c: [RPM_SMD_BB_CLK1] = &msm8916_bb_clk1,

Because the downstream kernel defines:
DEFINE_CLK_RPM_SMD_XO_BUFFER(ln_bb_clk1, ln_bb_clk1_ao, LN_BB_CLK1_ID);
DEFINE_CLK_RPM_SMD_XO_BUFFER_PINCTRL(ln_bb_clk1_pin, ln_bb_clk1_pin_ao,
LN_BB_CLK1_PIN_ID);
DEFINE_CLK_RPM_SMD_XO_BUFFER(ln_bb_clk2, ln_bb_clk2_ao, LN_BB_CLK2_ID);
DEFINE_CLK_RPM_SMD_XO_BUFFER_PINCTRL(ln_bb_clk2_pin, ln_bb_clk2_pin_ao,
LN_BB_CLK2_PIN_ID);
DEFINE_CLK_RPM_SMD_XO_BUFFER(ln_bb_clk3, ln_bb_clk3_ao, LN_BB_CLK3_ID);
DEFINE_CLK_RPM_SMD_XO_BUFFER_PINCTRL(ln_bb_clk3_pin, ln_bb_clk3_pin_ao,
LN_BB_CLK3_PIN_ID);
CLK_LIST(ln_bb_clk1),
CLK_LIST(ln_bb_clk1_ao),
CLK_LIST(ln_bb_clk1_pin),
CLK_LIST(ln_bb_clk1_pin_ao),
CLK_LIST(ln_bb_clk2),
CLK_LIST(ln_bb_clk2_ao),
CLK_LIST(ln_bb_clk2_pin),
CLK_LIST(ln_bb_clk2_pin_ao),
CLK_LIST(ln_bb_clk3),
CLK_LIST(ln_bb_clk3_ao),
CLK_LIST(ln_bb_clk3_pin),
CLK_LIST(ln_bb_clk3_pin_ao),
While your patch defines
DEFINE_CLK_SMD_RPM_XO_BUFFER(msm8998, bb_clk1, bb_clk1_a, 1);
DEFINE_CLK_SMD_RPM_XO_BUFFER(msm8998, bb_clk2, bb_clk2_a, 2);
DEFINE_CLK_SMD_RPM_XO_BUFFER_PINCTRL(msm8998, bb_clk3_pin, bb_clk3_a_pin, 3);
[RPM_SMD_BB_CLK1] = &msm8998_bb_clk1,
[RPM_SMD_BB_CLK1_A] = &msm8998_bb_clk1_a,
[RPM_SMD_BB_CLK2] = &msm8998_bb_clk2,
[RPM_SMD_BB_CLK2_A] = &msm8998_bb_clk2_a,
[RPM_SMD_BB_CLK3_PIN] = &msm8998_bb_clk3_pin,
[RPM_SMD_BB_CLK3_A_PIN] = &msm8998_bb_clk3_a_pin,
