drivers: misc: ti-st: Use int instead of fuzzy char for callback status
On mips and parisc: drivers/bluetooth/btwilink.c: In function 'ti_st_open': drivers/bluetooth/btwilink.c:174:21: warning: overflow in implicit constant conversion [-Woverflow] hst->reg_status = -EINPROGRESS; drivers/nfc/nfcwilink.c: In function 'nfcwilink_open': drivers/nfc/nfcwilink.c:396:31: warning: overflow in implicit constant conversion [-Woverflow] drv->st_register_cb_status = -EINPROGRESS; There are actually two issues: 1. Whether "char" is signed or unsigned depends on the architecture. As the completion callback data is used to pass a (negative) error code, it should always be signed. 2. EINPROGRESS is 150 on mips, 245 on parisc. Hence -EINPROGRESS doesn't fit in a signed 8-bit number. Change the callback status from "char" to "int" to fix these.
