Subject: perf_counter, x86: remove vendor check in fixed_mode_idx()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ef7b3e0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

perf_counter, x86: remove vendor check in fixed_mode_idx()

The function fixed_mode_idx() is used generically. Now it checks the
num_counters_fixed value instead of the vendor to decide if fixed
counters are present.

[ Impact: generalize code ]
