rsi: fix static checker warning
u32 pointer is changed to u16 and filled the value. Problem is solved by using local temporary variable. Below static checker warning was reported. drivers/net/wireless/rsi/rsi_91x_usb.c:400 rsi_usb_master_reg_read() warn: passing casted pointer 'value' to 'rsi_usb_reg_read()' 32 vs 16. Fixes: b97e9b94ad75c ("rsi: Add new host interface operations") Signed-off-by: Amitkumar Karwar <amit.karwar@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
