Hello Rui Miguel Silva,
The patch 60d789f3bfbb: "usb: isp1760: add support for isp1763" from
May 13, 2021, leads to the following static checker warning:
drivers/usb/isp1760/isp1760-hcd.c:276 isp1760_hcd_clear_and_wait()
warn: sleeping in atomic context
drivers/usb/isp1760/isp1760-hcd.c
268 static int isp1760_hcd_clear_and_wait(struct usb_hcd *hcd, u32 field,
269 u32 timeout_us)
270 {
271 struct isp1760_hcd *priv = hcd_to_priv(hcd);
272 u32 val;
273
274 isp1760_hcd_clear(hcd, field);
275
--> 276 return regmap_field_read_poll_timeout(priv->fields[field], val,
277 !val, 10, timeout_us);
^^
Originally this used to call read_poll_timeout() with 0 us_timeout (no
sleeping). The caller always holds a spin_lock.
278 }
regards,
dan carpenter
