The original does not copy symbolic link. Fix the following problems. 1. Copy symbolic link to the target folder 2. Follow link to copy the original file. This is for some firmwares link to other place which not mention in modinfo. (such as brcm/brcmfmac43455-sdio.bin links to cypress/cyfmac43455-sdio.bin. The cypress folder and firmware does not mention in any module.)
