Title
crypto: octeontx2 - remove CONFIG_DM_CRYPT check
Summary
In the Linux kernel, the following vulnerability has been resolved: crypto: octeontx2 - remove CONFIG_DM_CRYPT check No issues were found while using the driver with dm-crypt enabled. So CONFIG_DM_CRYPT check in the driver can be removed. This also fixes the NULL pointer dereference in driver release if CONFIG_DM_CRYPT is enabled. ... Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008 ... Call trace: crypto_unregister_alg+0x68/0xfc crypto_unregister_skciphers+0x44/0x60 otx2_cpt_crypto_exit+0x100/0x1a0 otx2_cptvf_remove+0xf8/0x200 pci_device_remove+0x3c/0xd4 __device_release_driver+0x188/0x234 device_release_driver+0x2c/0x4c ...
