[Buildroot] Kernel patches in Buildroot

[Joao Pinto]

Hi,
We are designing the procedure to release our software stack based on buildroot.
Could you please tell what is the advised method for including a kernel patch
set in buildroot? I typically use BR2_LINUX_KERNEL_PATCH where I indicate each
patch file. Is there a easier way like using BR2_GLOBAL_PATCH_DIR for example?

Thanks for your help!
