Devm_clk_get for clock error-CodePudding

 hw - & gt; CLK=devm_clk_get (& amp; Pdev - & gt; Dev, "spi"); 
If (IS_ERR (hw - & gt; CLK)) {
Dev_err (& amp; Pdev - & gt; Dev, "No clock for device \ n"); 
Err=PTR_ERR (hw - & gt; CLK); 
Goto err_no_pdata; 
}

Here is to print out: No clock for device
My device is:

 static struct s3c2410_spi_info spi1_info={/* by kite 2017.9.13 */
. Num_cs=0 XFF,/*, the choice of */
Bus_num=1, 
Set_cs=s3c24xx_spi_cs, 
} 

The static struct device_node spinp={
.name="spi", 
}; 

Struct platform_device s3c_device_spi1={
.name="s3c2410 - spi", 
Id=1, 
. Num_resources=ARRAY_SIZE (s3c_spi1_resource), 
.resource=s3c_spi1_resource, 
. Dev={
. Dma_mask=& amp; Samsung_device_dma_mask, 
. Coherent_dma_mask=DMA_BIT_MASK (32), 
Platform_data=https://bbs.csdn.net/topics/&spi1_info,/* by kite 2017.9.13 */
. Of_node=& amp; Spinp,//struct device_node * of_node; 
} 
};

This should be get the clock structure function, I don't know how he matches,
I try to change to: hw - & gt; CLK=devm_clk_get (NULL, "spi");
Because I see the first parameter to null is, matching the name of the results will go wrong,,,,
Solving the,,,,, I am 4.8.17 Kernel

Already solved...

I also encountered this problem, the drive from kernel5.2 transplantation to 2.6, also is the problem here
