Subject: mfd: atmel-hlcdc: Do not sleep in atomic context

From: Boris Brezillon <[email protected]>

commit 2c2469bc03d569c49119db2cccb5cb3f0c6a5b33 upstream.

readl_poll_timeout() calls usleep_range(), but regmap_atmel_hlcdc_reg_write() is called in atomic context (regmap spinlock held).

Replace the readl_poll_timeout() call by readl_poll_timeout_atomic().
