stable inclusion from stable-v6.6.33 commit 4e9293d660bff93927d6de5015f1544e85fe133f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 42c2d7d02977ef09d434b1f5b354f5bc6c1027ab ]
When both ACPI and OF are disabled, the dev_vdata variable is unused:
drivers/crypto/ccp/sp-platform.c:33:34: error: unused variable 'dev_vdata' [-Werror,-Wunused-const-variable]
This is not a useful configuration, and there is not much point in saving a few bytes when only one of the two is enabled, so just remove all these ifdef checks and rely on of_match_node() and acpi_match_device() returning NULL when these subsystems are disabled.
