[PATCH v5 14/22] coresight: funnel: remove multiple init calls from funnel driver
From: Tingwei Zhang <hidden>
Date: 2020-07-25 10:01:52
Subsystem:
arm/coresight framework and drivers, hardware tracing facilities, the rest · Maintainers:
Suzuki K Poulose, Alexander Shishkin, Linus Torvalds
From: Mian Yousaf Kaukab <redacted> Dynamic-funnel uses module_amba_driver to register. Whereas static-funnel uses builtin_platform_driver. Combine these init calls into a single module_init/exit pair in preparation to make the driver modular.
