pci_epf_alloc_space() already performs checks on the requested BAR size, and will allocate and set epf_bar->size to a size higher than the requested BAR size if some constraint deems it necessary. However, there are additional checks done in the function drivers like pci-epf-test.c, other than the existing checks in this API. And similar checks are proposed to other endpoint function drivers, see: https://lore.kernel.org/linux-pci/20240108151015.2030469-1-Frank.Li@nxp.com Having these checks scattered over different locations in multiple EPF drivers is not maintainable and makes the code hard to follow. Since pci_epf_alloc_space() already performs roundups and some checks, let's move the additional checks from pci-epf-test.c to pci_epf_alloc_space(). This makes the API more robust and also offloads the checks from the function drivers.
