[PATCH 19/19] block: nvme-scsi: make nvme_trans_get_blk_desc_len return unsigned

[Andrzej Hajda]

The function returns always non-negative values.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].

Hi,

To avoid problems with too many mail recipients I have sent whole
patchset only to LKML. Anyway patches have no dependencies.

Regards
Andrzej
