Subject: cmd: fpga: Move parameter checking for loadfs/loads
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=44d839bd5f3c7508c50fc083a48425188022d958;p=u-boot.git

cmd: fpga: Move parameter checking for loadfs/loads

There is no reason to check parameters in separate switch before main
one. This patch is simplifying error path and checking parameters right
after assignment.
