[yocto] unable to get checksum SRC_URI file could not be found

[jags gediya]

I am building yocto for freescale imx6sl evolution kit. For checking
in source code on svn , i have deleted all .git and .gitignore from
the meta directories. Then i have checkout the source code, and tried
to build that. While building i am getting the warning

Unable to get checksum for rfkill SRC_URI entry
dont.call.git.rev-parse.on.parent.dir.patch: file could not be found

What can be the reason of it?
Will it create any problem?

Thanks,
Jags
