linux-toradex.git/drivers/reset/reset-berlin.c, branch v4.20 Linux kernel for Apalis and Colibri modules reset: berlin: make it explicitly non-modular 2016-10-24T08:43:40+00:00 Paul Gortmaker paul.gortmaker@windriver.com 2016-06-13T18:03:34+00:00 ed4dba99cae80d14afb8ddcc677a2f547dd70162 The Kconfig currently controlling compilation of this code is: drivers/reset/Kconfig:config RESET_BERLIN drivers/reset/Kconfig: bool "Berlin Reset Driver" if COMPILE_TEST drivers/reset/Kconfig: default ARCH_BERLIN or arch/arm/mach-berlin/Kconfig:menuconfig ARCH_BERLIN arch/arm/mach-berlin/Kconfig: bool "Marvell Berlin SoCs" if ARCH_MULTI_V7 or arch/arm64/Kconfig.platforms:config ARCH_BERLIN arch/arm64/Kconfig.platforms: bool "Marvell Berlin SoC Family" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

The Kconfig currently controlling compilation of this code is:

drivers/reset/Kconfig:config RESET_BERLIN
drivers/reset/Kconfig:  bool "Berlin Reset Driver" if COMPILE_TEST
drivers/reset/Kconfig:  default ARCH_BERLIN

or

arch/arm/mach-berlin/Kconfig:menuconfig ARCH_BERLIN
arch/arm/mach-berlin/Kconfig:   bool "Marvell Berlin SoCs" if ARCH_MULTI_V7

or

arch/arm64/Kconfig.platforms:config ARCH_BERLIN
arch/arm64/Kconfig.platforms:   bool "Marvell Berlin SoC Family"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
