moduleparam: Resolve missing-field-initializer warning
Resolve a missing-field-initializer warning, that is produced by every reference to module_param_call, by using designated initialization for the first field. That is enough to silence the complaint. The message is only seen when doing a W=2 build. I happened to be using gcc 4.8.3, but I think most versions would produce the warning when it is enabled. It can either be silenced by using even a single designated initializer as I did here, or providing values for all of the fields. Because of the number of references to the macro, this change silences many warnings in W=2 builds. One instance of the full warning message looks like this: /home/share/git/nn-mdr/include/linux/moduleparam.h:198:16: warning: missing initializer for field ‘free’ of ‘struct kernel_param_ops’ [-Wmissing-field-initializers] static struct kernel_param_ops __param_ops_##name = \ ^ /home/share/git/nn-mdr/fs/fuse/inode.c:35:1: note: in expansion of macro ‘module_param_call’ module_param_call(max_user_bgreq, set_global_limit, param_get_uint, ^ /home/share/git/nn-mdr/include/linux/moduleparam.h:56:9: note: ‘free’ declared here void (*free)(void *arg); Signed-off-by: Mark Rustad <mark.d.rustad@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
