This patch series performs a clean up of the code in virtio_ring and virtio_pci, modifying it to conform with the Linux kernel coding style guidance [1]. The modifications ensure the code easy to read and understand. This small series does few short cleanups in the code. Patch-1 Remove unnecessary num zero check, which performs in power_of_2. Patch-2 Avoid using inline for small functions.
