'Squash' doesn't sound right since you are not squashing any code. > Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> > --- > drivers/pci/controller/pcie-mediatek-gen3.c | 14 +++----------- > 1 file changed, 3 insertions(+), 11 deletions(-) > > diff --git a/drivers/pci/controller/pcie-mediatek-gen3.c b/drivers/pci/controller/pcie-mediatek-gen3.c > index 0fac0b9fd785e463d26d29d695b923db41eef9cc..8c8c733a145634cdbfefd339f4a692f25a6e24de 100644 > --- a/drivers/pci/controller/pcie-mediatek-gen3.c > +++ b/drivers/pci/controller/pcie-mediatek-gen3.c > @@ -903,12 +903,6 @@ static int mtk_pcie_en7581_power_up(struct mtk_gen3_pcie *pcie) > pm_runtime_enable(dev); > pm_runtime_get_sync(dev); > > - err = clk_bulk_prepare(pcie->num_clks, pcie->clks); > - if (err) { > - dev_err(dev, "failed to prepare clock\n"); > - goto err_clk_prepare; > - } > - > val = FIELD_PREP(PCIE_VAL_LN0_DOWNSTREAM, 0x47) | > FIELD_PREP(PCIE_VAL_LN1_DOWNSTREAM, 0x47) | > FIELD_PREP(PCIE_VAL_LN0_UPSTREAM, 0x41) | > @@ -921,17 +915,15 @@ static int mtk_pcie_en7581_power_up(struct mtk_gen3_pcie *pcie) > FIELD_PREP(PCIE_K_FINETUNE_MAX, 0xf); > writel_relaxed(val, pcie->base + PCIE_PIPE4_PIE8_REG); > > - err = clk_bulk_enable(pcie->num_clks, pcie->clks); > + err = clk_bulk_prepare_enable(pcie->num_clks, pcie->clks); > if (err) { > dev_err(dev, "failed to prepare clock\n"); > - goto err_clk_enable; > + goto err_clk_init; err_clk_prepare_enable? But I usually prefer err labels to be named after their purpose. Like here, 'err_runtime_put_reset' so it gives the reader a sense of what the label is supposed to do. However, to keep the existing sematics, you can just name it err_clk_prepare_enable. - Mani > } > > return 0; > > -err_clk_enable: > - clk_bulk_unprepare(pcie->num_clks, pcie->clks); > -err_clk_prepare: > +err_clk_init: > pm_runtime_put_sync(dev); > pm_runtime_disable(dev); > reset_control_assert(pcie->mac_reset); > > -- > 2.47.0 >
