Hello Ben Young Tae Kim,
The patch 0ff252c1976d: "Bluetooth: hciuart: Add support QCA chipset
for UART" from Aug 10, 2015, leads to the following static checker
warning:
drivers/bluetooth/hci_qca.c:485 qca_debugfs_init()
warn: passing casted pointer '&qca->tx_vote' to 'debugfs_create_bool()' 1 vs 32.
drivers/bluetooth/hci_qca.c
482 &qca->ibs_recv_wakes);
483 debugfs_create_u64("ibs_recv_wake_acks", mode, ibs_dir,
484 &qca->ibs_recv_wacks);
485 debugfs_create_bool("tx_vote", mode, ibs_dir, (u32 *)&qca->tx_vote);
debugfs_create_bool() is stupid, because the name says bool but it
writes a u32. I am not sure why this is. Maybe because the sizeof
_Bool is not defined in C? Anyway, this will not work and will also
corrupt memory.
486 debugfs_create_u64("tx_votes_on", mode, ibs_dir, &qca->tx_votes_on);
487 debugfs_create_u64("tx_votes_off", mode, ibs_dir, &qca->tx_votes_off);
488 debugfs_create_bool("rx_vote", mode, ibs_dir, (u32 *)&qca->rx_vote);
^^^^
Same.
489 debugfs_create_u64("rx_votes_on", mode, ibs_dir, &qca->rx_votes_on);
490 debugfs_create_u64("rx_votes_off", mode, ibs_dir, &qca->rx_votes_off);
regards,
dan carpenter
