Subject: mlx4_core: Fix warning from min()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=70cb92539cd1b8e1dec935a68fc154ea0db3a177;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mlx4_core: Fix warning from min()

Recent cpumask changes changed num_possible_cpus() from returning an int
to returning an unsigned int.  This means that doing

    min(num_possible_cpus(), <int expression>)

now produces a warning like

    drivers/net/mlx4/main.c: In function 'mlx4_enable_msi_x':
    drivers/net/mlx4/main.c:915: warning: comparison of distinct pointer types lacks a cast

Fix this by using min_t(int, ...).
