2016-07-06clk: oxnas: make it explicitly non-modularPaul Gortmaker1-12/+3
The Kconfig currently controlling compilation of this code is: drivers/clk/Kconfig:config COMMON_CLK_OXNAS drivers/clk/Kconfig: bool "Clock driver for the OXNAS 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. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. 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.

2016-06-20clk: Fix return value check in oxnas_stdclk_probe()Wei Yongjun1-2/+2
In case of error, the function syscon_node_to_regmap() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
