  • 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:

  • On Asrock Z370M Pro4, it was observed that EC access was disabled after
    initially booting the system. As a result, the driver failed to load
    with
    nct6683: EC is disabled
    After a suspend/resume cycle, the driver loaded correctly.
    nct6683: Found NCT6683D or compatible chip at 0x2e:0xa20
    nct6683 nct6683.2592: NCT6683D EC firmware version 1.0 build 07/18/16

    Enable EC access after identifying the chip if disabled to fix the problem.
    Warn the user that the data it reports may be unusable, similar to other
    drivers for chips from Nuvoton.

  • Use DEVICE_ATTR_RW for read/write attributes. This simplifies the source
    code, improves readbility, and reduces the chance of inconsistencies.

    The conversion was done automatically using coccinelle. It was validated
    by compiling both the old and the new source code and comparing its text,
    data, and bss size.
