Subject: cmd: Remove unreachable code from netboot_nfs()
X-Git-Tag: submit/tizen/20201027.003535~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=67184eead8c8ef4bd340ac2155a2e573e39fc95d;p=platform%2Fkernel%2Fu-boot.git

cmd: Remove unreachable code from netboot_nfs()

rcode is always 0 (CMD_RET_SUCCESS) so last bootstage_error() call is never
executed. Remove it altogether with the rcode local variable.

This supresses following SVACE warning:

* UNREACHABLE_CODE: This statement in the source code might be unreachable during program execution.
     [unreachable] unreachable at cmd/net.c:312
     [rcode != 0 is always false because at this program point the variable rcode is always equal to 0]
      rcode != 0 is always false because at this program point the variable rcode is always equal to 0
      at cmd/net.c:309
