Subject: selftests/intel_pstate: fix operand expected error
X-Git-Tag: v6.12~83^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6553bfcb8499bf5e7e6d07d93f29459198dba798;p=platform%2Fkernel%2Flinux-amlogic.git

selftests/intel_pstate: fix operand expected error

Running "make kselftest TARGETS=intel_pstate" results in
the following errors:
- ./run.sh: line 90: / 1000: syntax error: operand expected
(error token is "/ 1000")
- ./run.sh: line 92: / 1000: syntax error: operand expected
(error token is "/ 1000")

This fix allows to have cross-platform compatibility when
using arithmetic expression with command substitutions.
