2013-01-04Drivers: scsi: remove __dev* attributes.Greg Kroah-Hartman1-2/+2
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2011-12-15[SCSI] be2iscsi: cleanup a min_t() callDan Carpenter1-2/+3
"sense_len" was declared as int type but actually it only stores a u16 value that comes from hardware. The cast to u16 in min_t() confuses static analysis because it truncates the int to u16 so I've fixed the declaration to reflect that "sense_len" is just a u16. Also there was a call to cpu_to_be16() which I've changed to be16_to_cpu(). The functions are equivalent, but obviously the hardware is big endian and we're doing the min_t() comparison on CPU endian values. This whole patch is just a cleanup and doesn't affect how the code works.

be2iscsi passes the boot functions its phba object which is allocated in the shost, but iscsi_ibft passes in a object allocated for each item to display. The problem is that iscsi_boot_sysfs was managing the lifetime of the object passed in and doing a kfree on release. This causes a double free for be2iscsi which frees the shost in its pci_remove. This patch fixes the problem by adding a release callback which the drivers can call kfree or a put() type of function (needed for be2iscsi which will do a get/put on the shost).
