The files directory is now split up into the files which are needed for every kernel version and the files only needed by kernel 4.1. The files in files-4.1 are already merged into mainline kernel 4.3. This patch only removed patches which were merged into mainline kernel 4.3.

Subject: [PATCH RFC] bcma: use two different initcalls if built-in
|

This is needed as we can't initialize bus during fs_initcall.
|
|
Initialization requires SPROM which depends on NVRAM which depends on
|
|
mtd. Since mtd, spi, nand, spi-nor use standard module_init, we have to
|
|
do the same in bcma.
|
|
Without this we'll try to initialize SPROM without having a ready SPROM
|
|
proviver registered using bcma_arch_register_fallback_sprom.

While this patch seems to work and I can compile bcma as built-in and
|
|
module, I'm not too proud of it. I don't really like these #if(n)def
|
|
tricks and I'm afraid bcma_modinit may be called even if
|
|
bcma_modinit_early failed.
|
|
|
|
Do you see any better idea of solving this?
