Hi all,
After merging the bluetooth tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
drivers/bluetooth/btmtksdio.c: In function 'btmtksdio_interrupt':
drivers/bluetooth/btmtksdio.c:470:2: warning: 'old_len' may be used uninitialized in this function [-Wmaybe-uninitialized]
print_hex_dump(KERN_ERR, "err sdio rx: ", DUMP_PREFIX_NONE, 4, 1,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
old_data, old_len, true);
~~~~~~~~~~~~~~~~~~~~~~~~
drivers/bluetooth/btmtksdio.c:376:15: note: 'old_len' was declared here
unsigned int old_len;
^~~~~~~
