In clk_boston_setup() then we'd have to put a ton of BUG()s in there to silence all the warnings. Right now the static checkers only care about kmalloc() but in a year or two they'll be clever enough to care about everything leaked in this function. I don't think adding BUG() calls is a good idea. Plus, I have a private static checker warning for that. When the BTRFS filesystem was merged 10 years ago it used to call BUG() all the time if allocations failed so I made a static checker warning to spot that anti-pattern... regards, dan carpenter
