[PATCH] idmouse cleanup and overflow fix
switched to simple_read_from_buffer(), killed broken use of min(). Incidentally, that use of min() had been fixed once, only to be reintroduced in commit 4244f724: [PATCH] USB: upgrade of the idmouse driver [snip] - if (count > IMGSIZE - *ppos) - count = IMGSIZE - *ppos; + count = min ((loff_t)count, IMGSIZE - (*ppos)); Note the lovely use of cast to shut the warning about misuse of min() up...
