From 9237f04e12cc385334043cd7cf84b74dcbda0256 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Wed, 30 Oct 2019 18:08:47 +0900 Subject: scsi: core: Fix scsi_get/set_resid() interface struct scsi_cmnd cmd->req.resid_len which is returned and set respectively by the helper functions scsi_get_resid() and scsi_set_resid() is an unsigned int. Reflect this fact in the interface of these helper functions. Also fix compilation errors due to min() and max() type mismatch introduced by this change in scsi debug code, usb transport code and in the USB ENE card reader driver.
