crypto: hisilicon/qm - set NULL to qm->debug.qm_diff_regs

2025-10-15T09:58:03+00:00

[ Upstream commit f0cafb02de883b3b413d34eb079c9680782a9cc1 ] When the initialization of qm->debug.acc_diff_reg fails, the probe process does not exit. However, after qm->debug.qm_diff_regs is freed, it is not set to NULL. This can lead to a double free when the remove process attempts to free it again. Therefore, qm->debug.qm_diff_regs should be set to NULL after it is freed.

crypto: hisilicon/debugfs - Fix debugfs uninit process issue

2024-07-11T10:49:02+00:00

[ Upstream commit 8be0913389718e8d27c4f1d4537b5e1b99ed7739 ] During the zip probe process, the debugfs failure does not stop the probe. When debugfs initialization fails, jumping to the error branch will also release regs, in addition to its own rollback operation. As a result, it may be released repeatedly during the regs uninit process. Therefore, the null check needs to be added to the regs uninit process.

crypto: hisilicon/qm - the command dump process is modified

2022-11-18T09:00:22+00:00

Reduce the function complexity by use the function table in the process of dumping queue. The function input parameters are unified. And maintainability is enhanced. Signed-off-by: Kai Ye Signed-off-by: Herbert Xu

crypto: hisilicon/qm - split a debugfs.c from qm

2022-11-18T09:00:22+00:00

Considering that the qm feature and debugfs feature are independent. The code related to debugfs is getting larger and larger. It should be separate as a debugfs file. So move some debugfs code to new file from qm file. The qm code logic is not modified. And maintainability is enhanced. Signed-off-by: Kai Ye Signed-off-by: Herbert Xu
