Subject: md: raid10: Fix compilation warning
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=38ffc01f38cc844ad2b81cdc9b0a087c4fc4c2b8;p=linux.git

md: raid10: Fix compilation warning

Remove the if statement around the call to sysfs_link_rdev() in
raid10_start_reshape() to avoid the compilation warning:

warning: suggest braces around empty body in an ‘if’ statement

when compiling with W=1.
