ieee802154: fix at86rf212_set_txpower() exit path
The commit 9b2777d6089bc ("ieee802154: add TX power control to wpan_phy") introduced the new function at86rf212_set_txpower() with the questionable check of the return of __at86rf230_write() in the exit path: 1) Both at86rf212_set_txpower() and __at86rf230_write() have the same return type. 2) Whatever __at86rf230_write() returns becomes the return value of at86rf212_set_txpower(). Thus, fix the exit path by getting rid of that check entirely. Signed-off-by: Jean Sacren <sakiwit@gmail.com> Cc: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de> Signed-off-by: David S.
