mtd: omap_elm: print interrupt resource using %pr · ce7f2853

由 Arnd Bergmann 提交于 12月 18, 2015

When CONFIG_LPAE is set on ARM, resource_size_t is 64-bit wide
and we get a warning about an incorrect format string for printing
the interrupt number in elm_probe:

drivers/mtd/nand/omap_elm.c: In function 'elm_probe':
drivers/mtd/nand/omap_elm.c:417:23: warning: format '%i' expects argument of type 'int', but argument 3 has type 'resource_size_t {aka long long unsigned int}' [-Wformat=]

This patch avoids the type mismatch by printing the interrupt as
a resource using the %pr format string.

mtd: bcm47xxnflash: really unregister NAND on device removal · 665d2c28

由 Brian Norris 提交于 12月 08, 2015

The field bcma_nflash::mtd is never set to be non-zero anywhere, but we
test for it in the removal path. So the MTD is never unregistered.

Also, we should use nand_release(), not mtd_device_unregister().

Finally, we don't need to use the 'platdata' for stashing/retrieving our
*driver* data -- that's what *_{get,set}_drvdata() are for.

So, kill off bcm_nflash::mtd, and stash the struct bcm47xxnflash in
drvdata instead. Also move the forward declaration of mtd_info up a bit,
since struct bcma_sflash should be using it.

Caught while inspecting other changes being made to this driver. Compile
tested only.

mtd: nand: denali: add missing nand_release() call in denali_remove() · 320092a0

由 Boris BREZILLON 提交于 12月 11, 2015

Unregister the NAND device from the NAND subsystem when removing a denali
NAND controller, otherwise the MTD attached to the NAND device is still
exposed by the MTD layer, and accesses to this device will likely crash
the system.

The BCM6368 has a NAND interrupt register with combined status and enable
registers.

As the BCM6328, BCM6362 and BCM6368 all use v2.1 controllers, the first
variant that will work with this driver is the BCM63268 using a v4.0
controller.

Set up the device by disabling and acking all interrupts, then handle
the CTRL_READY interrupt.

mtd: nand: r852: Remove unnecessary synchronize_irq() before free_irq() · 41849d49

由 Lars-Peter Clausen 提交于 11月 21, 2015

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

mtd: brcmnand: improve memory management · 081976bc

由 Julia Lawall 提交于 11月 19, 2015

This patch addresses two related memory management issues in the probe
function:

1. for_each_available_child_of_node performs an of_node_get on each
iteration, so a break out of the loop requires an of_node_put.

A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):

// <smpl>
@@
expression root,e;
local idexpression child;
@@

 for_each_available_child_of_node(root, child) {
   ... when != of_node_put(child)
       when != e = child
(
   return child;
|
+  of_node_put(child);
?  return ...;
)
   ...
 }
// </smpl>

2. The devm_kzalloc'd data is not used if brcmnand_init_cs fails.  Free it
immediately, using devm_kfree in this case, instead of waiting for the
remove function.
