scsi: be2iscsi: Fix an error handling path in beiscsi_dev_probe()

2021-07-20T14:21:15+00:00

[ Upstream commit 030e4138d11fced3b831c2761e4cecf347bae99c ] If an error occurs after a pci_enable_pcie_error_reporting() call, it must be undone by a corresponding pci_disable_pcie_error_reporting() call, as already done in the remove function.

memory: fsl_ifc: fix leak of private memory on probe failure

[ Upstream commit 8e0d09b1232d0538066c40ed4c13086faccbdff6 ] On probe error the driver should free the memory allocated for private structure. Fix this by using resource-managed allocation.

rtc: fix snprintf() checking in is_rtc_hctosys()

2021-07-20T14:21:15+00:00

[ Upstream commit 54b909436ede47e0ee07f1765da27ec2efa41e84 ] The scnprintf() function silently truncates the printf() and returns the number bytes that it was able to copy (not counting the NUL terminator). Thus, the highest value it can return here is "NAME_SIZE - 1" and the overflow check is dead code. Fix this by using the snprintf() function which returns the number of bytes that would have been copied if there was enough space and changing the condition from "> NAME_SIZE" to ">= NAME_SIZE".

power: supply: rt5033_battery: Fix device tree enumeration

2021-07-20T14:21:14+00:00

[ Upstream commit f3076cd8d1d5fa64b5e1fa5affc045c2fc123baa ] The fuel gauge in the RT5033 PMIC has its own I2C bus and interrupt line. Therefore, it is not actually part of the RT5033 MFD and needs its own of_match_table to probe properly. Also, given that it's independent of the MFD, there is actually no need to make the Kconfig depend on MFD_RT5033. Although the driver uses the shared header, there is no compile or runtime dependency on the RT5033 MFD driver.

PCI/sysfs: Fix dsm_label_utf16s_to_utf8s() buffer overrun

2021-07-20T14:21:14+00:00

[ Upstream commit bdcdaa13ad96f1a530711c29e6d4b8311eff767c ] "utf16s_to_utf8s(..., buf, PAGE_SIZE)" puts up to PAGE_SIZE bytes into "buf" and returns the number of bytes it actually put there. If it wrote PAGE_SIZE bytes, the newline added by dsm_label_utf16s_to_utf8s() would overrun "buf". Reduce the size available for utf16s_to_utf8s() to use so there is always space for the newline.
