memory: emif: Convert to DEFINE_SHOW_ATTRIBUTE

2020-09-20T16:59:19+00:00

Use DEFINE_SHOW_ATTRIBUTE macro to simplify the code. Along with this change, we get additionally: .owner = THIS_MODULE, .llseek = seq_lseek, 1. The llseek method is used to change the current read/write position in a file which can be ignored if you don't use it. 2. The owner is not even a method. Instead, it is a pointer to the module that “owns” this structure; it is used by the kernel to maintain the module's usage count which can be ignored.

memory: emif: Remove bogus debugfs error handling

2020-08-27T19:36:02+00:00

Callers are generally not supposed to check the return values from debugfs functions. Debugfs functions never return NULL so this error handling will never trigger. (Historically debugfs functions used to return a mix of NULL and error pointers but it was eventually deemed too complicated for something which wasn't intended to be used in normal situations). Delete all the error handling. Signed-off-by: Dan Carpenter Acked-by: Santosh Shilimkar Link: https://lore.kernel.org/r/20200826113759.GF393664@mwanda Signed-off-by: Krzysztof Kozlowski

memory: emif: Silence platform_get_irq() error in driver

2020-07-24T14:18:32+00:00

The platform_get_irq() already prints error message so there is no need to do it again in the driver. Signed-off-by: Krzysztof Kozlowski

memory: move jedec_ddr.h from include/memory to drivers/memory/

2019-06-17T11:45:21+00:00

Now that jedec_ddr_data.c was moved from lib/ to drivers/memory/, is included only from drivers/memory/. Make it a local header of drivers/memory/. The directory include/memory is now gone. While I am here, I also changed #include to . Because CONFIG_DDR is bool, jedec_ddr_data.c is never compiled as a module. Signed-off-by: Masahiro Yamada Signed-off-by: Olof Johansson

memory-EMIF: Use seq_putc() in emif_regdump_show()

2018-03-06T00:21:26+00:00

A single character (line break) should be put into a sequence. Thus use the corresponding function "seq_putc". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Santosh Shilimkar
