It doesn't correct the underlying issue, but I think this should go in even along with the real fix. The dmesg spamming has become a more serious problem for me than the underlying issue. Someone had a patch rejected that completely suppressed the message. >From my limited understanding, the hid spec allows an unlimited size for an hid report , but the kernel only allocated 32 bits, which was more than anything used at that time. The 32 bit version is doing some bit shifting and possibly endian correction with the 32 bit field, so I was not comfortable just extending it to 192 or 256 bits without a little more understanding. > Trivially, this could use "%s: ...", __func__, ...
