Why? Different files are missing different includes, this one needs
slab.h:

../drivers/usb/cdns3/host.c: In function ‘__cdns_host_init’:
../drivers/usb/cdns3/host.c:86:2: error: implicit declaration of function ‘kfree’; did you mean ‘vfree’? [-Werror=implicit-function-declaration]
  kfree(cdns->xhci_plat_data);
  ^~~~~
  vfree
