This is done to\navoid source code duplication. The problem, is that in the function\n'eqbr_irq_mask()' also calles the gpiolib function 'gpiochip_disable_irq()'\n\nThis generates the following warning trace in the log for every gpio on\nload.\n\n[    6.088111] ------------[ cut here ]------------\n[    6.092440] WARNING: CPU: 3 PID: 1 at drivers/gpio/gpiolib.c:3810 gpiochip_disable_irq+0x39/0x50\n[    6.097847] Modules linked in:\n[    6.097847] CPU: 3 UID: 0 PID: 1 Comm: swapper/0 Tainted: G        W          6.12.59+ #0\n[    6.097847] Tainted: [W]=WARN\n[    6.097847] RIP: 0010:gpiochip_disable_irq+0x39/0x50\n[    6.097847] Code: 39 c6 48 19 c0 21 c6 48 c1 e6 05 48 03 b2 38 03 00 00 48 81 fe 00 f0 ff ff 77 11 48 8b 46 08 f6 c4 02 74 06 f0 80 66 09 fb c3 <0f> 0b 90 0f 1f 40 00 c3 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40\n[    6.097847] RSP: 0000:ffffc9000000b830 EFLAGS: 00010046\n[    6.097847] RAX: 0000000000000045 RBX: ffff888001be02a0 RCX: 0000000000000008\n[    6.097847] RDX: ffff888001be9000 RSI: ffff888001b2dd00 RDI: ffff888001be02a0\n[    6.097847] RBP: ffffc9000000b860 R08: 0000000000000000 R09: 0000000000000000\n[    6.097847] R10: 0000000000000001 R11: ffff888001b2a154 R12: ffff888001be0514\n[    6.097847] R13: ffff888001be02a0 R14: 0000000000000008 R15: 0000000000000000\n[    6.097847] FS:  0000000000000000(0000) GS:ffff888041d80000(0000) knlGS:0000000000000000\n[    6.097847] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[    6.097847] CR2: 0000000000000000 CR3: 0000000003030000 CR4: 00000000001026b0\n[    6.097847] Call Trace:\n[    6.097847]  <TASK>\n[    6.097847]  ? eqbr_irq_mask+0x63/0x70\n[    6.097847]  ? no_action+0x10/0x10\n[    6.097847]  eqbr_irq_mask_ack+0x11/0x60\n\nIn an other driver (drivers/pinctrl/starfive/pinctrl-starfive-jh7100.c) the\ninterrupt is not disabled here.\n\nTo fix this, do not call the 'eqbr_irq_mask()' and 'eqbr_irq_ack()'\nfunction.
