Subject: [PATCH v3 1/3] i2c: pmcmsp: Use proper printk format for resource_size_t

resource_size_t should be printed with its own size-independent format
to fix warnings when compiling on 64-bit platform (e.g. with
COMPILE_TEST):

    drivers/i2c/busses/i2c-pmcmsp.c: In function ‘pmcmsptwi_probe’:
    drivers/i2c/busses/i2c-pmcmsp.c:276:25: warning:
        format ‘%x’ expects argument of type ‘unsigned int’,
        but argument 3 has type ‘resource_size_t {aka long long unsigned int}’ [-Wformat=]

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

Changes since v2:
1. Remove parentheses around res->start.

Changes since v1:
1. Use %pap, not %pa[p].
