Subject: crypto: jitterentropy - drop redundant delta check in jent_entropy_init
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=650f09718adc327c7dc50f6347580079fdb361f6;p=thirdparty%2Fkernel%2Flinux.git

crypto: jitterentropy - drop redundant delta check in jent_entropy_init

Since start_time = end_time - delta, start_time can only equal end_time
when delta is 0, making the explicit end_time == start_time check
redundant. Remove it.
