The first user of this function is the watchdog framework.Who is the 2nd user because I don't see any others. I don't see this being a widely used property.
Hi Rob, thanks for reviewing. There is only one use of this function in my patchset. I added this function after Jean-Christophe repeatedly suggested to add it. On Fri, Oct 5, 2012 at 1:16 PM, Jean-Christophe PLAGNIOL-VILLARD [off-list ref] wrote:
why I bother to comment *make this of generic* this is not watchdog specific other driver can use it
Maybe the idea was to have the helper ready when the dt support it's added to a drivers that use a "timeout" parameter. If it's for better i can just get rid of this function. I don't mind. Best regards
