Hello,
I found a bug in the most usb driver.
When the driver fails at
mdev->conf = kcalloc(num_endpoints, sizeof(*mdev->conf), GFP_KERNEL);
I got the following warning message:
[ 15.406256] kobject: '(null)' (ffff8881068f8000): is not initialized, yet kobject_put() is being called. [ 15.406986] WARNING: CPU: 3 PID: 396 at lib/kobject.c:720 kobject_put+0x6e/0x1c0 [ 15.410120] RIP: 0010:kobject_put+0x6e/0x1c0 [ 15.410470] Code: 01 75 29 4c 89 f8 48 c1 e8 03 80 3c 28 00 74 08 4c 89 ff e8 14 2e 73 ff 49 8b 37 48 c7 c7 c0 fc de 85 4c 89 fa e8 e2 61 21 ff <0f> 0b 49 8d 5f 38 48 89 df be 04 00 00 00 e8 df 2e 73 ff b8 ff ff [ 15.416529] Call Trace: [ 15.416896] hdm_probe+0xf3d/0x1090 [most_usb]
Since I'm not familiar with the driver, I ask for your help to solve the warning.
regards,
