2012-01-10drivers/rtc/interface.c: fix alarm rollover when day or month is out-of-rangeBen Hutchings
Commit f44f7f96a20a ("RTC: Initialize kernel state from RTC") introduced a potential infinite loop. If an alarm time contains a wildcard month and an invalid day (> 31), or a wildcard year and an invalid month (>= 12), the loop searching for the next matching date will never terminate. Treat the invalid values as wildcards.

2012-01-10drivers/rtc/: remove redundant spi driver bus initializationLars-Peter Clausen
In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register(), so we can drop the manual assignment.

2012-01-10[media] cx231xx: fix crash after load/unload/load of moduleThomas Petazzoni
The following sequence of commands was triggering a kernel crash in cdev_get(): modprobe cx231xx rmmod cx231xx modprobe cx231xx v4l2grab -n 1 The problem was that cx231xx_usb_disconnect() was not doing anything because the test: if (!dev->udev) return; was reached (i.e, dev->udev was NULL). This is due to the fact that the 'dev' pointer placed as intfdata into the usb_interface structure had the wrong value, because cx231xx_probe() was doing the usb_set_intfdata() on the wrong usb_interface structure. For some reason, cx231xx_probe() was doing the following: static int cx231xx_usb_probe(struct usb_interface *interface, const struct usb_device_id *id) { struct usb_interface *lif = NULL; [...] /* store the current interface */ lif = interface; [...] /* store the interface 0 back */ lif = udev->actconfig->interface[0]; [...] usb_set_intfdata(lif, dev); [...] retval = v4l2_device_register(&interface->dev, &dev->v4l2_dev); [...] } So, the usb_set_intfdata() was done on udev->actconfig->interface[0] and not on the 'interface' passed as argument to the ->probe() and ->disconnect() hooks. Later on, v4l2_device_register() was initializing the intfdata of the correct usb_interface structure as a pointer to the v4l2_device structure. Upon unregistration, the ->disconnect() hook was getting the intfdata of the usb_interface passed as argument... and casted it to a 'struct cx231xx *' while it was in fact a 'struct v4l2_device *'. The correct fix seems to just be to set the intfdata on the proper interface from the beginning. Now, loading/unloading/reloading the driver allows to use the device properly.

2012-01-10[SCSI] bfa: Implement LUN Masking feature using the SCSI Slave Callouts.Krishna Gudipati
This patch re-implements LUN Masking feature using SCSI Slave Callouts. With the new design in the slave_alloc entry point; for each new LUN discovered we check with our internal LUN Masking config whether to expose or to mask this particular LUN. We return -ENXIO (No such device or address) from slave_alloc for the LUNs we don't want to be exposed. We also notify the SCSI mid-layer to do a sequential LUN scan rather than REPORT_LUNS based scan if LUN masking is enabled on our HBA port, since a -ENXIO from any LUN in REPORT_LUNS based scan translates to a scan abort. This patch also handles the dynamic lun masking config change from enable to disable or vice-versa by resetting sdev_bflags of LUN 0 appropriately.

If ql4xdisablesysfsboot = 0 and sendtargets entry as boot index then driver does export sendtarget entries in sysfs but iscsistart does not do discovery. So in this case let driver do the discovery and login to the targets.

2012-01-10[SCSI] qla4xxx: Limit the ACB Default Timeout value to 12sNilesh Javali
A wrong default timeout value programmed in the adapter causes driver to wait for that much time while waiting for target discoveries to complete. This could add huge delays during the driver load time. To avoid this, limit the default timeout value to 12 seconds if the default timeout value set in adapter is less than 12 seconds and greater than 120 seconds.

2012-01-10[SCSI] libcxgbi: do not print a message when memory allocation failsThadeu Lima de Souza Cascardo
In alloc_pdu, libcxgbi tries to allocate a skb with GFP_ATOMIC, which may potentially fail. When it happens, the current code prints a warning message. When the system is under IO stress, this failure may happen lots of times and it usually scares users. Instead of printing the warning message, the code now increases the tx_dropped statistics for the ethernet interface wich is doing the iscsi task.

sym53c8xx_slave_destroy unconditionally assumes that sym53c8xx_slave_alloc has succesesfully allocated a sym_lcb. This can lead to a NULL pointer dereference (exposed by commit 4e6c82b).
