Drop the generic err_exit. The remaining operation to do from this goto statement is to cleanup the NAND allocations, so rename it. Signed-off-by:

Cosmetic change to give a meaning to all labels in this complicated error path. Signed-off-by:
-
Miquel Raynal authored
nand_release() basically calls mtd_device_unregister() and nand_cleanup(). Both helpers should be called after MTD device registration and NAND scan, respectively. Drop nand_release() and use the two helpers directly so that they fit the error path and the labels there. Signed-off-by:

ns_free() is the helper that is called symmetrically to ns_init() and so should free the same objects, including the partition names. Now, callers of ns_free() do not need to free this partition names themselves. Signed-off-by:

The nandsim device is allocated and initialized inside ns_init() by a call to ns_alloc_device(), free it on error. Signed-off-by:

The ns_init() function shall free the partition names allocated by ns_get_partition_name() on error. Signed-off-by:

The ns_alloc_device() helper has actually two distinct path. Handle errors in both of them. Signed-off-by:

Create a ns_debugfs_remove() helper for that and call it in ns_cleanup_module(). Signed-off-by:

Debugfs entries should be removed in the error path, so first, keep track of them. Signed-off-by:

Many function calls are done this way: if ((retval = func()) != 0) return retval; while we expect in the kernel function calls like: retval = func(); if (retval) return retval; Apply this change where possible and also use "ret" instead of "retval" in ns_init_module for consistency, as it is only used in this function.

Some functions are prefixed "nandsim_", others "ns_" and many are simply not prefixed at all. Make this file consistent by prefixing all functions by "ns_". This is a mechanical change. Sometimes the line is a bit reworked as well to fit the kernel coding style. For instance, there are several places where displayed strings are cut. When one of this line is changed because of the naming update, the two parts of the strings gets concatenated. Signed-off-by:

Symbolic permissions 'S_IRUSR' are not preferred. Checkpatch.pl advises to use octal permissions '0400'. Signed-off-by:

The nandsim object is called 'ns' almost everywhere, keep it that way everywhere for consistency. Signed-off-by:

Only v3.3-v5.0 have a different CS0 layout. Controllers before v3.3 use the same layout for every CS. Fixes: 27c5b17c ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller") Signed-off-by:

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced. Signed-off-by:

There is no reason that the failure of __gpmi_enable_clk() could lead to PM usage counter decrement. Signed-off-by:

Let's convert the driver to exec_op() to have one less driver relying on the legacy interface. Signed-off-by:

The rb-gpios semantics was undocumented and qi,lb60 (along with the ingenic driver) got it wrong. The active state encodes the NAND ready state, which is high level. Since there's no signal inverter on this board, it should be active-high. Let's fix that here for older DTs so we can re-use the generic nand_gpio_waitrdy() helper, and be consistent with what other drivers do. Suggested-by:

This helper is not very useful and very often people get confused: they use nand_release() instead of nand_cleanup(). Let's stop using nand_release() by calling mtd_device_unregister() and nand_cleanup() directly. Signed-off-by:
-
Miquel Raynal authored
nand_release() is supposed be called after MTD device registration. Here, only nand_scan() happened, so use nand_cleanup() instead. There is no real Fixes tag applying here as the use of nand_release() in this driver predates the introduction of nand_cleanup() in commit d44154f9 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible. However, pointing this commit as the culprit for backporting purposes makes sense even if this commit is not introducing any bug.
