commit a91918cd upstream. This iscsit_tpg_add_portal_group() function is only called from lio_target_tiqn_addtpg(). Both functions free the "tpg" pointer on error so it's a double free bug. The memory is allocated in the caller so it should be freed in the caller and not here. Fixes: e48354ce ("iscsi-target: Add iSCSI fabric support for target v4.1") Signed-off-by:

commit af15769f upstream. gcc-7 notices that the condition in mvs_94xx_command_active looks suspicious: drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active': drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context] This was introduced when the mv_printk() statement got added, and leads to the condition being ignored. This is probably harmless. Changing '&&' to '&' makes the code look reasonable, as we check the command bit before setting and printing it. Fixes: a4632aae ("[SCSI] mvsas: Add new macros and functions") Signed-off-by:

commit 432abf68 upstream. The generic command buffer entry is 128 bits (16 bytes), so the offset of tail and head pointer should be 16 bytes aligned and increased with 0x10 per command. When cmd buf is full, head = (tail + 0x10) % CMD_BUFFER_SIZE. So when left space of cmd buf should be able to store only two command, we should be issued one COMPLETE_WAIT additionally to wait all older commands completed. Then the left space should be increased after IOMMU fetching from cmd buf. So left check value should be left <= 0x20 (two commands). Signed-off-by:

commit 20979202 upstream. Fix bug https://bugzilla.kernel.org/show_bug.cgi?id=188561. Function wm831x_clkout_is_prepared() returns "true" when it fails to read CLOCK_CONTROL_1. "true" means the device is already prepared. So return "true" on the read failure seems improper. Signed-off-by:

commit 328cf692 upstream. If CONFIG_ETRAX_AXISFLASHMAP is not configured, the flash rescue image object file is empty. With recent versions of binutils, this results in the following build error. cris-linux-objcopy: error: the input file 'arch/cris/boot/rescue/rescue.o' has no sections This is seen, for example, when trying to build cris:allnoconfig with recently generated toolchains. Since it does not make sense to build a flash rescue image if there is no flash, only build it if CONFIG_ETRAX_AXISFLASHMAP is enabled. Reported-by:

commit d6214592 upstream. commit 0416e494 ("usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced") introduced a bug where we would leak DMA resources which would cause us to starve the system of them resulting in failing DMA transfers.

commit 3c3dd1e0 upstream. Function klsi_105_open() calls usb_control_msg() (to "enable read") and checks its return value. When the return value is unexpected, it only assigns the error code to the return variable retval, but does not terminate the exception path.

commit fde1faf8 upstream. A static usb-serial-driver structure that is used to initialise the interrupt URB was modified during probe depending on the currently probed device type, something which could break a parallel probe of a device of a different type. Fix this up by overriding the default completion callback for MCS7715 devices in attach() instead. We may want to use two usb-serial driver instances for the two types later.

commit 7e4da3fc upstream. By convention (according to doc) if function does not provide get_alt() callback composite framework should assume that it has only altsetting 0 and should respond with error if host tries to set other one. After commit dd4dff8b ("USB: composite: Fix bug: should test set_alt function pointer before use it") we started checking set_alt() callback instead of get_alt(). This check is useless as we check if set_alt() is set inside usb_add_function() and fail if it's NULL. Let's fix this check and move comment about why we check the get method instead of set a little bit closer to prevent future false fixes.
