A recent patch added a new function that is now unused whenever
CONFIG_OF is disabled:
drivers/misc/sram.c:342:12: error: 'atmel_securam_wait' defined but not used [-Werror=unused-function]
There is actually no reason for the #ifdef, because the driver
currently cannot be used in a meaningful way without CONFIG_OF,
and there is no compile-time dependency.
Removing that #ifdef and the respective of_match_ptr() avoids the
warning and simplifies the driver slightly.
Fixes: 2ae2e28852f2 ("misc: sram: add Atmel securam support")

I can not find the referenced commit on Torvald's branch,
won't it be rebased and get a changed commit hash after merge?

No, it won't be rebased, the merge will keep the commit ID.

It is in arm-soc (it went through the mach-at91 tree)
