Commit Message

Rikard Falkeborn March 4, 2021, 11:07 p.m. UTC
In stmpe_devices_init(), the start and end field of these structs are
modified, so they can not be const. Add a comment to those structs that
lacked it to reduce the risk that this happens again.

This reverts commit 8d7b3a6dac4eae22c58b0853696cbd256966741b.

Fixes: 8d7b3a6dac4e ("mfd: stmpe: Constify static struct resource")
Reported-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Changes
V1-V2: Add comments to the structs that they are dynamically modified
       Rewrite commit message.
