ipmi_si: Fix wrong return value in try_smi_init()

2020-10-29T09:07:49+00:00

[ Upstream commit 8fe7990ceda8597e407d06bffc4bdbe835a93ece ] On an error exit path, a negative error code should be returned instead of a positive return value.

ipmi: ipmb_dev_int: add quick fix for raw I2C type registration

2020-10-09T21:47:19+00:00

This commit adds quick fix for cases of run time registration through sysfs. It should be fixed later by adding parsing code for ipmb_id instead. This is a temporary fix. Do not upstream it. Signed-off-by: Jae Hyun Yoo

char: ipmi: Add clock control logic into Aspeed LPC KCS driver

2020-10-05T22:24:25+00:00

If LPC KCS driver is registered ahead of lpc-ctrl module, LPC KCS block will be enabled without heart beating of LCLK until lpc-ctrl enables the LCLK. This issue causes improper handling on host interrupts when the host sends interrupt in that time frame. Then kernel eventually forcibly disables the interrupt with dumping stack and printing a 'nobody cared this irq' message out. To prevent this issue, all LPC sub-nodes should enable LCLK individually so this patch adds clock control logic into the LPC KCS driver. Signed-off-by: Jae Hyun Yoo Signed-off-by: Vernon Mauery

tpm: Unify the mismatching TPM space buffer sizes

2020-08-19T06:27:01+00:00

commit 6c4e79d99e6f42b79040f1a33cd4018f5425030b upstream. The size of the buffers for storing context's and sessions can vary from arch to arch as PAGE_SIZE can be anything between 4 kB and 256 kB (the maximum for PPC64). Define a fixed buffer size set to 16 kB. This should be enough for most use with three handles (that is how many we allow at the moment). Parametrize the buffer size while doing this, so that it is easier to revisit this later on if required.

agp/intel: Fix a memory leak on module initialisation failure

2020-08-19T06:26:23+00:00

[ Upstream commit b975abbd382fe442713a4c233549abb90e57c22b ] In intel_gtt_setup_scratch_page(), pointer "page" is not released if pci_dma_mapping_error() return an error, leading to a memory leak on module initialisation failure. Simply fix this issue by freeing "page" before return.
