Hi all,
After merging the percpu tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:
drivers/scsi/qla2xxx/qla_attr.c: In function 'qla2x00_process_vendor_specific':
drivers/scsi/qla2xxx/qla_attr.c:2150: warning: 'req_data' may be used uninitialized in this function
drivers/scsi/qla2xxx/qla_attr.c:2152: warning: 'req_data_len' may be used uninitialized in this function
If the first "goto done_unmap_sg;" in this function is followed, the
req_data will be tested even though it has not been assigned to yet and
if it is non zero, it and req_data_len will be passed to
dma_free_coherent() while still uninitialised.
Introduced by commit 9a069e196767d7b87184fd8d8211d22bb5b9c0b8 ("[SCSI]
qla2xxx: Add BSG support for FC ELS/CT passthrough and vendor commands").
The compiler also produces these:
drivers/scsi/qla2xxx/qla_attr.c:2144: warning: 'command_sent' may be used uninitialized in this function
drivers/scsi/qla2xxx/qla_attr.c:2146: warning: 'type' may be used uninitialized in this function
but I can't easily tell if they are false positives.
