When ti_iodelay_pinconf_init_dev() fails, no error return code of ti_iodelay_probe() is assigned. To fix this bug, ret is assigned with the return value of ti_iodelay_pinconf_init_dev(), and then ret is checked.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2018-06-12treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

2017-04-07pinctrl: core: Fix pinctrl_register_and_init() with pinctrl_enable()Tony Lindgren
Recent pinctrl changes to allow dynamic allocation of pins exposed one more issue with the pinctrl pins claimed early by the controller itself. This caused a regression for IMX6 pinctrl hogs. Before enabling the pin controller driver we need to wait until it has been properly initialized, then claim the hogs, and only then enable it. To fix the regression, split the code into pinctrl_claim_hogs() and pinctrl_enable(). And then let's require that pinctrl_enable() is always called by the pin controller driver when ready after calling pinctrl_register_and_init().

2017-01-13pinctrl: core: Fix regression caused by delayed work for hogsTony Lindgren
Commit df61b366af26 ("pinctrl: core: Use delayed work for hogs") caused a regression at least with sh-pfc that is also a GPIO controller as noted by Geert Uytterhoeven <geert@linux-m68k.org>. As the original pinctrl_register() has issues calling pin controller driver functions early before the controller has finished registering, we can't just revert commit df61b366af26. That would break the drivers using GENERIC_PINCTRL_GROUPS or GENERIC_PINMUX_FUNCTIONS. So let's fix the issue with the following steps as a single patch: 1. Revert the late_init parts of commit df61b366af26. The late_init clearly won't work and we have to just give up on fixing pinctrl_register() for GENERIC_PINCTRL_GROUPS and GENERIC_PINMUX_FUNCTIONS. 2. Split pinctrl_register() into two parts By splitting pinctrl_register() into pinctrl_init_controller() and pinctrl_create_and_start() we have better control over when it's safe to call pinctrl_create(). 3. Introduce a new pinctrl_register_and_init() function As suggested by Linus Walleij <linus.walleij@linaro.org>, we can just introduce a new function for the controllers that need pinctrl_create() called later. 4. Convert the four known problem cases to use new function Let's convert pinctrl-imx, pinctrl-single, sh-pfc and ti-iodelay to use the new function to fix the issues. The rest of the drivers can be converted later. Let's also update Documentation/pinctrl.txt accordingly because of the known issues with pinctrl_register().

2017-01-09pinctrl: Introduce TI IOdelay configuration driverNishanth Menon
SoC family such as DRA7 family of processors have, in addition to the regular muxing of pins (as done by pinctrl-single), a separate hardware module called IODelay which is also expected to be configured. The "IODelay" module has it's own register space that is independent of the control module and the padconf register area. With recent changes to the pinctrl framework, we can now support this hardware with a reasonably minimal driver by using #pinctrl-cells, GENERIC_PINCTRL_GROUPS and GENERIC_PINMUX_FUNCTIONS. It is advocated strongly in TI's official documentation considering the existing design of the DRA7 family of processors during mux or IODelay reconfiguration, there is a potential for a significant glitch which may cause functional impairment to certain hardware. It is hence recommended to do as little of muxing as absolutely necessary without I/O isolation (which can only be done in initial stages of bootloader). NOTE: with the system wide I/O isolation scheme present in DRA7 SoC family, it is not reasonable to do stop all I/O operations for every such pad configuration scheme. So, we will let it glitch when used in this mode. Even with the above limitation, certain functionality such as MMC has mandatory need for IODelay reconfiguration requirements, depending on speed of transfer. In these cases, with careful examination of usecase involved, the expected glitch can be controlled such that it does not impact functionality. In short, IODelay module support as a padconf driver being introduced here is not expected to do SoC wide I/O Isolation and is meant for a limited subset of IODelay configuration requirements that need to be dynamic and whose glitchy behavior will not cause functionality failure for that interface. IMPORTANT NOTE: we take the approach of keeping LOCK_BITs cleared to 0x0 at all times, even when configuring Manual IO Timing Modes. This is done by eliminating the LOCK_BIT=1 setting from Step of the Manual IO timing Mode configuration procedure. This option leaves the CFG_* registers unprotected from unintended writes to the CTRL_CORE_PAD_* registers while Manual IO Timing Modes are configured. This approach is taken to allow for a generic driver to exist in kernel world that has to be used carefully in required usecases.
