Re: [PATCH v2 4/4] Staging: rts5208: Fix a format specifier for dev_err

[Fabio Falzoi]

Hi Micky,

in the latest linux-tree sources, lun field in struct scsi_device from
include/scsi/scsi_device.h is a u64:

        unsigned int id, channel;
        u64 lun;
        unsigned int manufacturer;

so we get a compiler warning if we keep the %u specifier.

Regards,
Fabio
