Hi... Khem Raj
First of all, Thanks for the swift reply.
Let me brief the case.
Actually, I'm dealing with the TP-Link Bluetooth dongle
I have been enabled it's suitable drivers
However, the things not working well
After some googling, i got to know that to work with the TP-Link Bluetooth dongle, I'll have to apply the patch by making some changes at the busb.c and hci_ldisc.c files
And that's how, I have created it's patches by git diff --no-index command
FYI: I have meta-custom layer, in which i have created the recpies-kernel/linux/stm32mp1 directory
I have stored, all 2 patches in to the stm32mp1 files
in linux file, i have created the .bbappend file called linux-stm32mp_%.bbappend
For the instance, i have added the all to patches path in to the .bbappend file at SRC_URI
Now, My problem is, during the baking of the custom image I'm getting the following errors
"can't find file to patch at input line 5"
Error logs
For your reference, i have attached the contents of the .bbappend file and patch here

In above .bbappend file, the last two patches are for this modules which i need to modify
Once of the patch contents are mentioned at here

I have also attached both of these patches here
I guess, there might be some issue with the actual source file location mentioned in to the patches
but, I'm not sure
Pl. suggest me the right solution
Thanks
Mahendra
