So your two local branches 'master' and 'linux-next' both point at the
same commit, 5717922.

"git checkout <branchname>" is to check out the local branch name.  You
expect "git checkout master" and then "git checkout linux-next" to check
out two different commits because linux-next _should_ have been updated to
the latest from sfr repository.  But it appears to me that that is not the
case.

Perhaps "git fetch linux-next" hasn't been run, before "git checkout" was
attempted?
