Subject: [SCSI] esp_scsi: Make cur_residue and tot_residue signed.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=582fb6c03a0e89d05e4efa8a3e4bd09d0942dadc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[SCSI] esp_scsi: Make cur_residue and tot_residue signed.

Many of the overflow checks test whether the value has
gone negative, and we want to retain such checks.
