13 years agoARM: OMAP: change get_context_loss_count ret value to int
Tomi Valkeinen [Thu, 9 Jun 2011 13:56:23 +0000 (16:56 +0300)]
ARM: OMAP: change get_context_loss_count ret value to int

get_context_loss_count functions return context loss count as u32, and
zero means an error. However, zero is also returned when context has
never been lost and could also be returned when the context loss count
has wrapped and goes to zero.

Change the functions to return an int, with negative value meaning an
error.

OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the
hsmmc code handles the returned value as an int, with negative value
meaning an error, this patch actually fixes hsmmc code also.

Commit d6504acd2125984c61dce24727dd3842d0144015 ("OMAP2+: hwmod:
remove OMAP_CHIP*") tests the inverse condition of what it should be
testing for the return value from omap_hwmod_register().  This causes
several IP blocks to not be registered on several OMAP3 family devices.

Fixing that bug also unmasked another bug, originally reported by
Chase Maupin <chase.maupin@ti.com> and then subsequently by Abhilash K
V <abhilash.kv@ti.com>, which caused SmartReflex IP blocks to be
registered on SoCs that don't support them.

13 years agosysfs: Make sysfs_rename safe with sysfs_dirents in rbtrees.
Eric W. Biederman [Tue, 1 Nov 2011 14:06:17 +0000 (07:06 -0700)]
sysfs: Make sysfs_rename safe with sysfs_dirents in rbtrees.

In sysfs_rename we need to remove the optimization of not calling
sysfs_unlink_sibling and sysfs_link_sibling if the renamed parent
directory is not changing.  This optimization is no longer valid now
that sysfs dirents are stored in an rbtree sorted by name.

Move the assignment of s_ns before the call of sysfs_link_sibling.  With
no sysfs_dirent fields changing after the call of sysfs_link_sibling
this allows sysfs_link_sibling to take any of the directory entries into
account when it builds the rbtrees, and s_ns looks like a prime canidate
to be used in the rbtree in the future.

There are plausible reasons for architectures to provide their own
versions of csum_partial_copy_nocheck and csum_tcpudp_magic.
By protecting these, the architecture can still re-use the

lib/string.c: fix strim() semantics for strings that have only blanks

Commit 84c95c9acf0 ("string: on strstrip(), first remove leading spaces
before running over str") improved\7f the performance of the strim()
function.

Unfortunately this changed the semantics of strim() and broke my code.
Before the patch it was possible to use strim() without using the return
value for removing trailing spaces from strings that had either only
blanks or only trailing blanks.

Now this does not work any longer for strings that *only* have blanks.

Before patch: "   " -> ""    (empty string)
After patch:  "   " -> "   " (no change)

I think we should remove your patch to restore the old behavior.

The description (lib/string.c):

 * Note that the first trailing whitespace is replaced with a %NUL-terminator

=> The first trailing whitespace of a string that only has whitespace
   characters is the first whitespace

The patch restores the old strim() semantics.

leds: save the delay values after a successful call to blink_set()

When calling the hardware blinking function implemented by blink_set(),
the delay_on and delay_off values are not preserved across calls.

Fix that and make the "timer" trigger work as expected when hardware
blinking is available.

BEFORE the fix:
  $ cd /sys/class/leds/someled
  $ echo timer > trigger
  $ cat delay_on delay_off
  0
  0
  $ echo 100 > delay_on
  $ cat delay_on delay_off
  0
  0
  $ echo 100 > delay_off
  $ cat delay_on delay_off
  0
  0

AFTER the fix:
  $ cd /sys/class/leds/someled
  $ echo timer > trigger
  $ cat delay_on delay_off
  0
  0
  $ echo 100 > delay_on
  $ cat delay_on delay_off
  100
  0
  $ echo 100 > delay_off
  $ cat delay_on delay_off
  100
  100

My GPIOs are on an I2C port expander, so we must use the *_cansleep()
variant of the GPIO functions.  This is was not being done in
create_gpio_led().

We can change gpio_get_value() to gpio_get_value_cansleep() because it is
only called from the platform_driver probe function, which is a context
where we can sleep.

Only tested on my gpio_cansleep() system, but it seems safe for all
systems.

13 years agodrivers/leds/leds-lm3530.c: add __devexit_p where needed
Axel Lin [Tue, 1 Nov 2011 00:12:15 +0000 (17:12 -0700)]
drivers/leds/leds-lm3530.c: add __devexit_p where needed

According to the comments in include/linux/init.h:

"Pointers to __devexit functions must use __devexit_p(function_name), the
wrapper will insert either the function_name or NULL, depending on the config
options."

We have __devexit annotation for lm3530_remove(), so add __devexit_p to
the `struct i2c_driver'.
