Remove 'type' argument from access_ok() function

2019-01-04T02:57:57Z

Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds

ALSA: wss: Fix invalid snd_free_pages() at error path

2018-11-24T18:55:59Z

Some spurious calls of snd_free_pages() have been overlooked and remain in the error paths of wss driver code. Since runtime->dma_area is managed by the PCM core helper, we shouldn't release manually. Drop the superfluous calls. Reviewed-by: Takashi Sakamoto Cc: Signed-off-by: Takashi Iwai

ALSA: opti92xx-ad1848: Use the standard fall-through annotation

2018-10-12T07:31:32Z

As a preparatory patch for the upcoming -Wimplicit-fallthrough compiler checks, replace with the standard "fall through" annotation at the right places. They have to be put right before the next labels. Signed-off-by: Takashi Iwai

ALSA: isa: Remove empty init and exit

2018-08-03T14:11:35Z

For a sake of code simplification, remove the init and the exit entries that do nothing. Notes for readers: actually it's OK to remove *both* init and exit, but not OK to remove the exit entry. By removing only the exit while keeping init, the module becomes permanently loaded; i.e. you cannot unload it any longer! Signed-off-by: Takashi Iwai
