Remove the if statement around the calls to sysfs_link_rdev() to avoid the compilation warnings: warning: suggest braces around empty body in an ‘if’ statement when compiling with W=1. For the call to sysfs_create_link() generating the same warning, use the err variable to store the function result, avoiding triggering another warning as the function is declared as 'warn_unused_result'.
